[jwenting]

no, you're beyond help... :(

You do take care to actually remember what the first input was, do you?
Or more likely you don't but should.

You did not answer iamthwee question...
All depends what you do and also how much usability you give a user. Do you colect only 2 variables or you let user insert as many values us he/she wish including bracklets, square, power etc? You want simple calculator like windows have or you try to created scientific?
