check out as guest only

[fabvincent]

Hi, I need to have my virtuemart working as a check out as guest only.
The template I'm using is acting strange and if I don't check the "allow account creation on check out", the cart won't go through the regular process and stops at step 2. Well, what I need to know is what file controls the renderControlButtons($this,$rview); that I have on the edit_address.php so I could just hide out the checkout and register button.

Thanks a lot.

Nevermind boys and girls,
I just realized that the function was at the beginnig of the page and the rendercontrolButtons just called it from below. I got it now, everything is ok. Thanks.
