[LUA] bad argument #1 to 'ipairs' (table expected, got nil)

[Lejjo]

What I wonder is what does this error output mean?

bad argument #1 to 'ipairs' (table expected, got nil)

The code looks like this:

function spellSys:setCombatParam(paramType, value, ...)
	for _, v in ipairs(arg) do <--This is where the error occur when I look in my GUI
		setCombatParam(self:getCombat(v), paramType, value)
	end
end

Thanks in advance!

The first argument you've thrown into the function ipairs is nil, Lua (not LUA..) expects a table. You give it 'arg' which is an unassigned variable, aka nil.

The thing is that it worked on TFS before but now it doesnt anymore. Back then I used TFS for 8.1 and now I use TFS 9.1
