IF...THEN won't let numbers to be summed

[skimask]

Don't know why one works and the other doesn't.
I just stick with what does work...
I know, no help, but it's the facts...


Also, I just looked thru your code.
There's an END statement in the middle before GAME_SPEED.
You probably don't want that in there.

And a couple of your for/next statements, you don't specifically tell PBP which variable you are 'next'ing with your 'for'.
Might help, might not...
