I have successfully completed a shopping cart with UD that submits the order to Authorize.net. Unfortunately I am unable to get the receipt page to work. Authorize.net POST the transaction information page to me but I cannot seem to get the information to display on the page. I have tried several pieces of code similar to below.

<% Request.form("x_first_name" %>

Nothing is working, please help!

Thanks.
Terrell.
