Table inside of a table getting a value

[Walkerbo]

Hi all

I have a table within a table where I need to access a value to build a button.

So far I can build the buttons successfully and they display their value, however, when click the button to use that value to print a message only the top button prints the expected string, the second prints nothing, and each subsequent button prints nil.

Here is my chunk;

DeathKnightChatScrollFrame.buttons = {}
for index = 1, NumberList.scrollButtonNumber do
    DeathKnightChatScrollFrame.buttons[index] =
        CreateFrame("Button", "btn" .. index, DeathKnightChatScrollParent, "OptionsListButtonTemplate")
    button = DeathKnightChatScrollFrame.buttons[index]
    button:SetSize(NumberList.scrollSpellFrameWidth, NumberList.phraseTextButtonHeight)
    button:SetPoint("TOPLEFT", 8, -(index - 1) * NumberList.phraseTextButtonHeight - 8)
    button:SetScript(
        "OnClick",
        function(self)
            print("Test Print -  ", DeathKnightSpellList[self.index].spellChatList[index], index) -- debug --
        end
    )
end

This is the table layout;


These are the print results;


My questions are why can I not grab the string values using the following syntax,

DeathKnightSpellList.spellChatList[self.index]

And what is the proper syntax to correctly use the string value in the second table?
