Please help

This is the first iem i will be using the Security wizard and i have built my DB using a DAP interface. I want to create two groups of users:

1) one with full access and:
2) access limiteed to just a few of the DAP pages.

I can not figure out how to set that up, it seems that you can only limit the permsision but that seems global and not to each object/page/table blabh blah blah.

Any assitance would be greatly aprreciated.
