[Resolved] a form problem........

[anne]

hello..

i have a form with several textboxes and select tags.

if i want a user to key in 2 different values in 2 separate
textboxes, how can i make php to add the 2 values
and automatically display the sum in a third text box ?
(the calculation involves several values retrieved from database)

another thing is, how can i make it work without making the
page to reload ? because after that the user still have to key in
several more values into the form.

someone please help me.........

You can't. For PHP to process you have to reload the page. What you CAN do, is have the first 2 textboxes on one part of your page, and have the 3rd in an html iframe, and write a javascript that will submit to that iframe.

The easiest route would be a multi step process. get as much info as you can in each step, and take them trhough mulitple pages to get to the end result. Many sites do it.
