InfoPath Dev

I have a form developed without any code.  I created a form user role named Admins and in that role are only three people.

Then on a simple text field on the form I have set the conditional formatting as "Users current role not set to Admins", then Read Only.

However, I am having a problem that anyone opening the form can type in the field.

Any suggestions?

Thanks

Never mind. Sorry.  I added a second user group of All Domain Users, changed the conditional formatting and it worked.
