    Please help if you can.
    My problem is that i have simple paypal form. When user select 10 accounts then below textbox shows amount to be paid. But when i click at paypal it again multiply with accounts and shows multiple amount at paypal page.

    For example if you select 10 then amount will be 18.5$ but after clicking at pay button it shows amount at paypal page $185.00 




    <body>
<form name="frm1" action="https://www.paypal.com/cgi-bin/webscr" method="post">
    <input type="hidden" name="cmd" value="_xclick">
    <input type="hidden" name="business" value="accounts@freelanceswitch.com"><br />
    <strong>How Many Acounts you want</strong>
<select name="quantity" onchange="calculate()" id="quantity">
   		<option value="5">5</option>
   		<option value="10">10</option>
   		<option value="15">15</option>
   		<option value="20">20</option>
   		<option value="25">25</option>
   		<option value="30">30</option>
  </select>
<br />
    <input type="hidden" name="no_shipping" value="0">
    <input type="hidden" name="no_note" value="1">
    <input type="hidden" name="currency_code" value="USD">
    <input type="hidden" name="lc" value="AU">
    <input type="hidden" name="bn" value="PP-BuyNowBF">
	<input type="hidden" name="return" value="http://net.tutsplus.com/payment-complete/">
	<br />
	<p>$
      <input type="text" name="amount" id="amount" value="0" readonly="readonly"/>
  <br />

      <input type="submit" value="Pay with PayPal!">
  </p>
</form>
<script type="text/javascript">
	function calculate (){
		ac=document.getElementById('quantity').value;
		var z=1.85;
		
		total =ac*z;
		document.frm1.amount.value=total;	
		}
	
</script>
</body>
