Problem with Price Tracker

[Maliena]

I'm getting this error...

user:/AddOns/PriceTracker/MathUtils.lua:9: operator / is not supported for string / number
stack traceback:
user:/AddOns/PriceTracker/MathUtils.lua:9: in function '(anonymous)'
[C]: in function 'table.sort'

I've tried using the updated Garkin version and that still gives me the error,I've even tried the link in the other thread for Price Tracker and that didn't work either. I dont know what to do and i'm really frustrated. HALP!
