Hi Dee,
You no longer need the HOP page. In fact, the HOP will no longer work on Oct 1, 2014 (tomorrow). Cybersource is decommissioning the HOP and replacing it with Secure Acceptance.
You will need to setup a Secure Acceptance Profile in Cybersource's control panel. Follow the steps here:
http://www.cybersource.com/resources/collateral/pdf/Secure_Acceptance_WM_Quick_Start_Guide .pdf
From there you will get the "AccessKey", "ProfileID", and "SecretKey" you need to make the "payment_form.cfm" and the "payment_confirmation.cfm" above work in place of the HOP.
