Keep input value on form submit

[hlforr]

I have a form as below on a page pricelist.php. On submit, it uses the code in submit.php to print a price next to the form on pricelist.php depending on the choices submitted in the form. On submit, I need the values of the first two fields to be retained. Is there a way to do this?

I'm not sure if I hear your question straight. Are you saying on submit you don't want to submit the first two fields values or you want to also keep it for later use?

[hlforr]

Sorry, I wasn't too clear in my post. What I meant was that I want all the values to submit but that when a user fills in the form the values in the first two fields (the number of yearbooks and the number of pages in each yearbook) need to be retained so that if the user wants to see the price of another type of yearbook, they don't have to fill in the values for the number of yearbooks and pages over again.

Retaining values across 'pages' requires storage. The usual method is session data usually stored in variables... $_SESSION['somename'].
