I'm trying to add a discount code to the paypal button, The javascript works and says the discount code is valid but isn't taking the discount off the amount when you click the buy now button to pay.

Can anyone help me please

<form action="https://www.paypal.com/cgi-bin/webscr" method="post">
<p>Please click on the link to pay</p>

The javascript is:

var discnt = 0;   // no default percent discount



var coupons = new Array (  // place to put coupon codes

  "coup1",                 // 1st coupon value - comma seperated

  "coup2",                 // 2nd coupon value - add all you want

  "coup3"                  // 3rd coupon value
);
var coupdc  = new Array ( 5,10,15
 // place to put discounts for coupon vals
);
var coupval = "(blanket)"; // what user entered as coupon code
function ChkCoup () {      // check user coupon entry
var i;
  discnt = 0;              // assume the worst
  for (i=0; i<coupons.length; i++) {
    if (coupval == coupons[i]) {
      discnt = coupdc[i];  // remember the discount amt
      alert ("This is a valid promo code! \n\n" + discnt + "%" +" discount now in effect.");
      return;

    }
  }
  alert ("'" + coupval + "'  is not a valid promo code!");
}
function Pound (val) {      // force to valid Pound amount
var str,pos,rnd=0;
  if (val < .995) rnd = 1;  // for old Netscape browsers
  str = escape (val*1.0 + 0.005001 + rnd);  // float, round, escape
  pos = str.indexOf (".");
  if (pos > 0) str = str.substring (rnd, pos + 3);
  return str;
}
function ReadForm (obj1) {  // apply the discount
var amt,des;
  amt = obj1.amount_<?php echo $iloop; ?>.value*1.0;       // base amount
  des = obj1.basedes_<?php echo $iloop; ?>.value;           // base description
  if (discnt > 0) {                   // only if discount is active
    amt = Pound (amt - (amt * discnt/100.0));
    des = des + ", " + discnt + "%" + "dis, COUP = " + coupval;
  }
  obj1.amount.value = Pound (amt);
  obj1.item_name.value = des;
