Field set as required isn't

We are using Document Seller on a client site, SMHConsultants.com. We've added a field, "Fax" and set it to "Show" and "Required" but the form doesn't require this field when you submit. Basically ignores it.

Is this a known problem?

Thanks.

BTW, what is the latest version of Documents Seller that runs on Joomla 1.5? (I know, I know...)

Hi Jim

The latest version for Joomla 1.5 is 2.7.0. We only maintain that version for Joomla 1.5 now, no new features will be added !

What version you are using ? Maybe that version contains the bugs and it causes the issue !
