No Coupon choice in Gift Certificate menu

I have a working cart installed (www.vetsgear.com) - It's not been announced, but needs to be...

I'd like to send out a coupon for preferred customers from another site. I'm unable to create a coupon, because coupons are missing from the admin gv/coupon menu.

I haven't installed any admin modules. Any help would be appreciated.
Thanks!

Try admin > Gift Certificate/Coupon > insert > and create a new coupon

When I go to Admin-> Gift Certificate/Coupons my choices are

• Gift Certificate Queue
• Mail Gift Certificate
• Gift Certificates sentI have gift certificates working fine. I have not tried coupons until just now. I've spent a couple of hours looking at the forum, and must be missing something. Either in my store install, or in the forum.

Did you turn on the Discount Coupons in Modules ... Order Total ...

Be sure that Discount Coupons ot_coupon is installed ...
