That may prevent the error but it won't actually work the way you probably expect. When you just write "GetZoneText" that means you're passing a reference to that function -- you're not calling it and passing the string it returns, which is what I think you proably want.

BGCallouts:func(GetZoneText())

When you use a colon between the table name and the function name, you're using "method notation" which means there's a hidden first argument called "self" that refers to the table. You should avoid mixing dots and colons, especially if you are just getting started with Lua.

If you have this:

local MyAddon = CreateFrame("Frame", "MyAddonFrame")

Then these ways of defining a function do the same thing:

function MyAddon:PrintStuff(msg) -- note the colon
   DEFAULT_CHAT_FRAME:AddMessage(self:GetName() .. ": " .. msg)
end

function MyAddon.PrintStuff(self, msg) -- note the dot
   DEFAULT_CHAT_FRAME:AddMessage(self:GetName() .. ": " .. msg)
end

And regardless of which style you used, these ways of calling the function do the same thing:

MyAddon:PrintStuff("Hello!")

MyAddon.PrintStuff(MyAddon, "Hello!")

... but this way of calling it will result in an error:

MyAddon.PrintStuff("Hello!")

... and this way of defining the function is not the same:

function MyAddon.PrintStuff(msg)
   DEFAULT_CHAT_FRAME:AddMessage(MyAddon:GetName() .. ": " .. msg)
   -- ^ You have to write "MyAddon" instead of "self" here
   -- because no variable named "self" is defined in this scope.
end

If you defined it that way, you can only call it like this:

MyAddon.PrintStuff("Hello!")

If you defined it that way and try to call it in either of the first two ways, you will get an error.
