Security on the Form

Hi everyone!

Maybe my problem want be areal problem for you.
I had made a Access databse and use two forms:
one is for user who had administrator permission and second which will be used by users to find some records:readonly.I'll try with VB to make security on this second form, but i think that i will need help to write it down.
My database is on network.

Can anybody help me with that or give me a hint?

Thank you in advance,
Zinka
