Is it possible to do the following?

Here are the steps I do:
Tools
Forms
Design a form
I select the appointment form
the appointment form comes up in design mode with 10 tabs (appointment, P.2,
P.3, P.4, P.5, P.6, scheduling, all fields,properties and actions.
I want to change the informaion on the first tab that says appointments. I
am unable to do that
