TOPIC: "Register" button redirect

Hello,
I'm using dtdonate and JEvents 1.5 on Joomla 1.5.10.
In the JEvents view, once the "register" button is clicked, the registration page comes up fine, but I lose all assigned modules as the site now thinks it's on the home page.
How can I adjust the "register" link to add an itemid to the end of the link?
Thank you for your help
Mark
