Jim is right on here.  I'd even save a step.  Make the value of $submit 
an integer, then use that integer to create the name of a variable 
variable, from which you get the needed data.

Form...
   <input type="hidden" name="item2" value="PA03" />
   <input type="submit" name="submit" value="2" />

Script...
   $itemvar = "item$submit";
   echo 'item chosen is: ' . $$itemvar;

This eliminates the need to go through a lot of if or switch statements
and makes it easy to add and remove items because you don't need to 
update those if or switch statements.

Again, Jim is on target.  This is really the way to go for several
reasons.  Most importantly, -- yes, I'm bringing this back to the data
vaidation thread :) -- it keeps people from editing the cost before
submitting the form.  Also, it obviates the need for any hidden fields
at all by allowing you to just put the product ID value into the submit
buttons, like this:

   <input type="submit" name="ProductID" value="PA03" />

If you don't have database access, you can keep the product information 
in a text file or an include file.

Enjoy,
