I have mentioned in the initial email that if I just allow users to type stuff, it passes the form back to itself and works. However, what I want > to do is to allow users click one radio button/checkbox, and use that value to determine which "select menu" to bring up. However, the information I am only interested in storing, is the value of the select menu and not the radio button/checkbox. > > Am I making sense here? > > Alice > > ------- > > http://sperling.com http://ancientstones.com http://earthstones.com > > _________________________________________________________________ > The New Busy think 9 to 5 is a cute idea.

It doesn't matter if you submit more form elements than you need, just don't use them when the form is submitted to the php script. Thanks, Ash http://www.ashleysheridan.co.uk
