WoWInterface - Global (a nil value) Problem!

Well, you're loading your Lua twice, you're using XML, everything is global, your buttons are not parented to your frame, and you're trying to set scripts to functions that you didn't define anywhere, so there are a lot of problems... just get rid of the whole XML file and replace your Lua file with this:

Code:

local frame = CreateFrame("Frame", "FinalFrame", UIParent)

-- you may want to actually position the frame somewhere, give it visible regions, etc.



local button =CreateFrame("Button", "$parentButton", frame, "UIPanelButtonTemplate")

button:SetPoint("BOTTOMRIGHT", UIParent, 0, 66)

button:SetWidth(80)

button:SetHeight(22)

button:SetText("Twelve")

button:SetScript("OnClick", function(self, mouseButton)

    -- do something here when clicked

end)



local chanbutton = CreateFrame("Button", "$parentChannelButton", UIParent, "UIPanelButtonTemplate")

chanbutton:SetPoint("BOTTOMRIGHT", UIParent, 0, 88)

chanbutton:SetWidth(160)

chanbutton:SetHeight(22)

chanbutton:SetText("Fav. Channel")

chanbutton:SetScript("OnClick", function(self, mouseButton)

    -- do something here when clicked

end)

The reason nothing is defined is because I didn't post the whole script.

The only error when I post the whole lua script is that final() is a nil value.

I NEED to use XML to call the function, its part of the project.

Could you just tell me why its saying Final is a nil value?

Heres the whole lua script

Lua Code:

function finalproj()
    print("So I guess this works");
    mybutton = CreateFrame("Button","mybutton",UIParent,"UIPanelButtonTemplate")
    mybutton:SetPoint("BOTTOMRIGHT",0,66)
    mybutton:SetWidth(80)
    mybutton:SetHeight(22)
    mybutton:SetText("Twelve")
    mybutton:SetScript("OnClick", buttontest)
    
    chanbutton = CreateFrame("Button","chanbutton",UIParent,"UIPanelButtonTemplate")
    chanbutton:SetPoint("BOTTOMRIGHT",0,88)
    chanbutton:SetWidth(160)
    chanbutton:SetHeight(22)
    chanbutton:SetText("Fav. Channel")
    chanbutton:SetScript("OnClick", channeljoin)
end
--[[function partybutton()
    print("Would you like to add them to your party?");
    accbutton = CreateFrame("Button","accbutton",UIParent,"UIPanelButtonTemplate")
    accbutton:SetPoint("BOTTOMRIGHT",0,22)
    accbutton:SetWidth(80)
    accbutton:SetHeight(22)
    accbutton:SetText("Accept")
    accbutton:SetScript("OnClick", InviteUnit("target"))
    
    decbutton = CreateFrame("Button","decbutton",UIParent,"UIPanelButtonTemplate")
    decbutton:SetPoint("BOTTOMRIGHT",0,44)
    decbutton:SetWidth(80)
    decbutton:SetHeight(22)
    decbutton:SetText("Decline")
    decbutton:SetScript("OnClick", break)
    
    trdbutton = CreateFrame("Button","trdbutton",UIParent,"UIPanelButtonTemplate")
    trdbutton:SetPoint("BOTTOMRIGHT",0,66)
    trdbutton:SetWidth(80)
    trdbutton:SetHeight(22)
    trdbutton:SetText("Trading Request")
    trdbutton:SetScript("OnClick", InitiateTrade("target"))
end--]]
 
function buttontest()
    print("AW DUDE THIS BUTTON ROCKS!");
    if UnitIsUnit("player", "target") then
        print("This players name is " .. UnitName);
        print("They are a " .. UnitClass("target") .. " " .. UnitRace("target"));
        print("They currently have " .. UnitHealth("target") .. " health, out of " .. UnitMaxHealth("target") .. " health.");
        partybutton();
    end
end--]]

    end

        print("That is not the healer, please target the healer")
    end
    
    if UnitGroupRolesAssigned("target") == HEALER then
        messagedman == "target"
        print("That is the healer. When you are at 50% or lower health, this addon will automatically send a message to the healer")
    end
    
    if(UnitHealthMax("player") / UnitHealth("player") <=50% then
            SendChatMessage("HEAL ME!","WHISPER","nil",messagedman);
    end

This used to work yesterday, barely anything has changed.
I used comments so I could try and debug it.
