Please can someone help me!!

I have created a couple of Oracle Forms, but they should have 2 levels of access full access (password protected) which will allow queries, data entry, delete and update privileges and restricted access - which allows only queries to be made.

I've created two roles admin and queryonly, but I've no idea how to tie everything together, I connect upto my database in the form builder, but I can't find any info about how to grant levels of access on the forms to my roles.

Does anyone know how to do this?

Many thanks
