Ahh,
The problem is that you're not submitting the form. You're making a new
request via Javascript.
Instead, do this:
Give the form an id:
<form method="post" name="form1" id="form1">
Then in your select box use javascript to subit the form.
<select name="item_num" onChange="document.getElementById('form1').submit()">
Then you'll be able to read the submitted form information from the request
object. You also won't need to put all the querystring building code in the
option tags.
