Thanks, this did the trick!
Thanks, this did the trick, however, I had to remove the ?> from both entries as it was putting two of these: /> /> before the buttons on the submit page.
<input type="hidden" name="cancel_return" id="cancel_return" value="https://therugrack.com/ecommerce /pp_cancel.php"); ?>" />
<input type="hidden" name="return" id="return" value="https://therugrack.com/ecommerce /checkout_success.php"); ?>" />
This is the code I used after removing them:
<input type="hidden" name="cancel_return" id="cancel_return" value="https://therugrack.com/ecommerce /pp_cancel.php"); />
<input type="hidden" name="return" id="return" value="https://therugrack.com/ecommerce /checkout_success.php"); />
