Can't get the saferpay form to show up

Hi!

I'm probably just missing a tiny thing but can't get the saferpay gateway module to work correctly.

I installed the module, activated it, configured it (admin/store/settings/payment/edit/methods), gave my Account ID and checked the 3 checkbox underneath.

Now I was expecting something like a form to give financial data when the customer go to the checkout page but instead, I just have a radio-button selected: Saferpay - Secure Payment on the Internet.
and in a box under is a short sentence (sth like, "click finalize the command to finish the process" (it's not the exact words, cause I translated it in french and can't remember the exact sentence ^_^).

Well, the point is, the expected form never shows up.

Am I doing something wrong or did I misunderstood the role of the uc_saferpay module?

Thanks you for taking a bit of time to enlight me.
