query not working with paypal link
when i submit the form using the index3.php link , i use the isset fucntion to check if the button has been pressed if true a query updates a datasbase by decrementing the the "quantity" colum. 

using the index3.php link works

<form action="index3.php" method="post">

but when with replace index3.php with the paypal link. the query does not work.

<form action="https://www.paypal.com/cgi-bin/webscr" method="post">

it must be something to do with the external paypal link , i would really be happy if i could get the query to work with the paypal link

anyone an ideas ?????
