[Zope] ZSQL Methods in different directories

[yuba@cyberback.com]

Can I place ZSQL Methods in seperate directories than the DTML Methods which=
 call them=2E Well, I *know* I can, but I'm having trouble when the ZSQL Met=
hods are not in a parent directory to be acquired=2E  If I place the ZSQL Me=
thods in a folder under "main", and then create a folder "Members" under mai=
n, how do I call the "AddMemberSQL" method from the "Members" directory?  I'=
ve tried all sorts of combinations, but none seem to work=2E  How can I do t=
his?

Thanks!
