HTML works that way. If you go to ClubMac you'll see we calculate the totalWeight on an intermediate page before showing the shipping price on the next page. Formulas.db cuts down on one extra step, but the only way to calculate information 'live' on a single page is to use Java or JavaScript.It's got nothing to do with where you put the form variables in the HTML -- first, last, or in the middle, they all get sent to the next page regardless, and CGIs can't see them until the user does something.Grant Hulbert, V.P.
