Need help with Advertizer Manager please

What Advertizer Manager does...

Adds a dropdown menu to the checkout process page and forces the customer to select where they saw the advertizing that drove them to purchase products from your store.

OK, I just had a site re-design and when my web designer updated and transferred over my files, it seems something changed with this contribution.

In the past with the drop down, it was "required" to fill something out, anything, or select from the drop down menu before you could proceed, but now anyone can bypass it all together and just checkout. Most people won't bother filling out a selection or form if they don't have to.

What has to be changed in order for the contribution to "require" the information before proceeding. She did my cart last year so she doesn't remember what she did to make that a requirement and not an option that you can bypass..

It worked before....:-(
