The error is in the SetScript on line 149. SetScript accepts 2 parameters, the script and the function that should be called.

cb:SetScript("OnClick", setLoc(i))

This will generate an error This will happen if the onclick handler is called:

setLoc(i)(...)

Errors. This IS correct:

cb:SetScript("OnClick", function(i) setLoc(i) end)

Which will be called like this(function:2FJ39 is the link to the local function created by function(i) setLoc(i) end):

function:2FJ39(...)

And the most neat way is this:

cb:SetScript("OnClick", setLoc)

Which will get called like this:

setLoc(...)

Which is what we want.

Final thing, you are concatenating the i variable in your setLoc function, don't you mean this?

i = i:GetName()
