I didn't really look through the code too thoroughly, but:
form1.balance.value + form1.buy.value;
did you want += here?
form1.balance.value + form1.buy.value;
did you want += here?

That fix worked for me. I checked it in firefox, the only problem with += would be string concatenation, but it was definitely adding digits for me...

If you want to add numbers, try
total = parseInt(form1.balance.value) + parseInt(form1.buy.value); Programming today is a race between software engineers striving to build bigger and better idiot-proof programs, and the Universe trying to produce bigger and better idiots. So far, the Universe is winning.
