Hi Doug.
Thanks for the great tools and clear explanations.

(Please pardon my rudimentary questions)

>It's best to avoid using compound (ie. more than one field) keys in joins between tables. Say WELLUNIT is the foreign key field to the other table. Create an index on it *and* create one on WELLUNIT + WELLINSP as your candidate key. Then, use the WELLUNIT tag for RI.


? I chose 'Edit RI' and the Grid/Builder comes up, but I can't change the Tag values. How do I get back there?

Thanks,
Sylvia
