Answer to your second problem:
I thik that yours is an overflow problem. The resultof the operation
b1*100 it's to big for an interger (integer, I supose) and returns the
negative value.
Maybe the operation 'b1/avgb1*100' (all together, in the same line)
works fine.
Another solution is to force the float operation with a dot: 'b1*100./avgb1'
