html form value in php...

Hi! I do know that if I use any TEXTBOX or HIDDEN value in html and click the SUBMIT button,. After going to the next webpage, I can find the data in the $_POST[''] data.... But what about the SELECT attribute for multiple rows. (Sort of work like a List box)? I haven't seen anything liek this that would work, so do I have to use the input HIDDEN value instead, like entering or updating each row of the SELECT tag instead? Thanks, Scott
