WoWInterface - OnReceiveDrag OnClick scripts on the same button

Hi all

I have a couple of issues my code.

I have a list of items that I can add to and remove from.

I am have created a button that can receive an item from a drag-drop, or click-drop or remove and item via it's itemID.
I have a text entry box that will accept itemID's and I can confirm the text entry is working as expected.
I can also confirm the remove item function works as it is used elsewhere in the addon.

When I try to remove an item either by drag-drop, click-drop or via itemID nothing happens.
Bugsack is not detecting any errors.
If I remove the tests that remove function works correctly.

Here are my functions:

Lua Code:

local function removeItemFromList(searchList, searchItemLink)
    for k, v in pairs(searchList) do
        if v.itemLink == searchItemLink then
            table.remove(searchList, k)
        end
    end
    if searchList == AVKGlobalSellTable and AVKGlobalSettings.Sell.sirlm then
        print(ColourList.textBluePrefixSuffix .. searchItemLink .. " removed from your global sell list.")
    elseif searchList == AVKCharacterSellTable and AVKGlobalSettings.Sell.sirlm then
        print(ColourList.textBluePrefixSuffix .. searchItemLink .. " removed from " .. playerName .. "'s sell list.")
    elseif searchList == AVKGlobalDestroyTable and AVKGlobalSettings.Destroy.dirlm then
        print(ColourList.textBluePrefixSuffix .. searchItemLink .. " removed from your global destroy list.")
    elseif searchList == AVKCharacterDestroyTable and AVKGlobalSettings.Destroy.dirlm then
        print(ColourList.textBluePrefixSuffix .. searchItemLink .. " removed from " .. playerName .. "'s destroy list.")
    elseif searchList == AVKGlobalProtectTable and AVKGlobalSettings.Protect.pirlm then
        print(ColourList.textBluePrefixSuffix .. searchItemLink .. " removed from your global protect list.")
    elseif searchList == AVKCharacterProtectTable and AVKGlobalSettings.Protect.pirlm then
        print(ColourList.textBluePrefixSuffix .. searchItemLink .. " removed from " .. playerName .. "'s protect list.")
    end
end
 
local function checkItemOnCharacterProtectList(cursorItemID)
    for k, v in pairs(AVKCharacterProtectTable) do
        if v.itemID == cursorItemID then
            return true
        end
    end
end

And here is my onclick script;

Lua Code:

AardvarkSpecialRemoveItemProtectCharacterButton:SetScript(
    "OnClick",
    function(self, button)
        if GetCursorInfo() then
            itemType, itemID, itemLink = GetCursorInfo()
            if itemType ~= "item" then
                textBoxMessages(InvalidRemove)
            elseif not checkItemOnCharacterProtectList(itemLink) then
                textBoxMessages(ItemNotFound)
            else
                removeItemFromList(AVKCharacterProtectTable, itemLink)
            end
        else
            textItemID = AardvarkSpecialRemoveTextBox:GetNumber()
            local itemName, itemLink = GetItemInfo(textItemID)
            C_Timer.After(
                VariableList.sellDelay,
                function(self)
                    if itemType ~= "item" then
                        textBoxMessages(InvalidRemove)
                    elseif not checkItemOnCharacterProtectList(itemLink) then
                        textBoxMessages(ItemNotFound)
                    else
                        removeItemFromList(AVKCharacterProtectTable, cursorItemLink)
                    end
                end
            )
        end
        avkUpdateCharacterProtectList()
        ClearCursor()
    end
)

Also, I need to work out how to correctly use two button scripts on the same button.

I need to have the button to get the itemlink of any item drag-dropped or clickdropped.

Also, I need to find out how to have multiple button scripts work together.

I know that I can use :SetScript("OnReceiveDrag", myFunctionToRemoveItemFromList); however, the function that I need to run requires two variables.

I thought I had it correct with the following;

Lua Code:

AardvarkSpecialRemoveItemProtectCharacterButton:SetScript(
    "OnReceiveDrag",
    function(self, button)
        if GetCursorInfo() then
            itemType, itemID, itemLink = GetCursorInfo()
            if itemType ~= "item" then
                textBoxMessages(InvalidRemove)
            elseif not checkItemOnCharacterProtectList(itemLink) then
                textBoxMessages(ItemNotFound)
            else
                removeItemFromList(AVKCharacterProtectTable, itemLink)
            end
        end
        avkUpdateCharacterProtectList()
        ClearCursor()
    end
)
AardvarkSpecialRemoveItemProtectCharacterButton:SetScript(
    "OnClick",
    function(self, button)
        if GetCursorInfo() then
            itemType, itemID, itemLink = GetCursorInfo()
            if itemType ~= "item" then
                textBoxMessages(InvalidRemove)
            elseif not checkItemOnCharacterProtectList(itemLink) then
                textBoxMessages(ItemNotFound)
            else
                removeItemFromList(AVKCharacterProtectTable, itemLink)
            end
        else
            textItemID = AardvarkSpecialRemoveTextBox:GetNumber()
            local itemName, itemLink = GetItemInfo(textItemID)
            C_Timer.After(
                VariableList.sellDelay,
                function(self)
                    if itemType ~= "item" then
                        textBoxMessages(InvalidRemove)
                    elseif not checkItemOnCharacterProtectList(itemLink) then
                        textBoxMessages(ItemNotFound)
                    else
                        removeItemFromList(AVKCharacterProtectTable, cursorItemLink)
                    end
                end
            )
        end
        avkUpdateCharacterProtectList()
        ClearCursor()
    end
)

but this too does not work, evedn though I am not getting any errors.

I am really stuck with this one.
Any help would be great.
