changing input text value

[zang8027]

i got this working. When the user types in the box and clicks out of it, the url changes to add ?quan=[whatever they entered]

 

But when it refreshes, the input box resets to the default value. Is there a way that when it refreshes, the value will now equal whatever quan=?

 

<script type="text/javascript">
function upperCase(x)
{
var y=document.getElementById(x).value;
self.location='index.php?quan=' + y ;
}
</script>

 

<?php include('../includes/head2.php') ?>
<div id="promo">
	<h1>Order in bulk, and save some cash!</h1>
	<p>When you order a quantity of 500 or more, we'll pay your shipping and handling for you, as a token of our appreciation!</p>
</div>
</div>
<div id="middle">
	<div id="inside">
	<h2>Pricing and Order Info</h2>
	<div class="price1">
	<img src="../images/order.gif"/><br/>
	<!-- Form goes here -->
	<form target="paypal" action="https://www.paypal.com/cgi-bin/webscr" method="post">

<?php

  //recieve the passed amount
$amount = $_REQUEST['quan'];

if(isset($_REQUEST['quan'])){
if($amount > 0)
{
   if($amount <= 1000)
   {
   echo '<input type="hidden" name="quantity_1" value="'.$amount.'" />';
   echo '<input type="hidden" name="amount_1" value="0.19">';
   }
}

if($amount >=1001)
{
   if($amount <=5000)
   {
      //post form to paypal with $amount and 0.18
   echo '<input type="hidden" name="quantity_1" value="'.$amount.'" />';
   echo '<input type="hidden" name="amount_1" value="0.18">';
   }

}

if($amount >=5001)

   if($amount <=10000)
   {
      //post form to paypal with $amount and 0.17
