Error with runes

I'm getting this error any time my screen reloads:

36x BasicUI\Modules\Powerbar.lua:316: attempt to perform arithmetic on local 'start' (a nil value)
[string "@BasicUI\Modules\Powerbar.lua"]:316: in function <BasicUI\Modules\Powerbar.lua:314>
[string "@BasicUI\Modules\Powerbar.lua"]:495: in function <BasicUI\Modules\Powerbar.lua:480>

self = 1
start = nil
duration = nil
runeReady = nil
(*temporary) = <function> defined =[C]:-1
(*temporary) = 173940.047000
(*temporary) = 173940.047000
(*temporary) = nil
(*temporary) = "attempt to perform arithmetic on local 'start' (a nil value)"
floor = <function> defined =[C]:-1
this is the code block that is coming from:
	local function CalcRuneCooldown(self)
		local start, duration, runeReady = GetRuneCooldown(self)
		local time = floor(GetTime() - start)
		local cooldown = ceil(duration - time)

		if (runeReady or UnitIsDeadOrGhost('player')) then
			return '#'
		elseif (not UnitIsDeadOrGhost('player') and cooldown) then
			return cooldown
The bold part of the code is line 316 where the error is coming from any suggestions?

You're calling the function with self? Is it a number as it should be?
Edit: Ah, now I see its a number. Perhaps its called too early before runes are available?

If a function can return a value you cant use in a formula you should make sure to only use it when a value valid.
The cataclysm broke the world ... and the pandas could not fix it!
