We are setting up an e-commerce site for the family business and I can't figure out how to code the registration page to submit form results and open a "thank you" page. I've got this code from another programmer and we are successful in posting to the customer database but I can't get the "thank you" page to open.

To start the form:

<form id="Registration" class="validate" action="https://www.hostcompany.com/store/default.aspx" method="post" name="Registration">

Submit button code:

<input type="hidden" name="ReplyURL" value="thank_you_for_registering.htm" />
<input id="buttonlogin" class="createaccount" type="submit" value="Submit Securely" />
