Oh I thought you meant an error in the editor. An assert I dunno, are the values in the array definitely numbers? Try int() around the calculation to convert it if it produces a number as a string.
awsome dude ! yes that worked, your an angel!
weird, it worked with just one int for the first array call, i put the second one to see what happens.
the first part was seen has a string and the second part a number?
now its giving me a preety big numbers, gonna see if i can convert it to a float or something, but its not very important, dont think i intend to show the numbers to the player.
