How to edit frmOptions

I'm a newbie to edit Option Forms. From the Tabscrpt there are 5 Groups. I can only edit on the first front Group but not the others.
My questions are :
1. How to edit the other remaining Tabscript on this Option Form?
2. How to change name, ie, I want to replace names Group 1, Group2, etc to something more specific to their function.

Thank you in advance! :)

Click Custom in the Property window after focusing the SSTab1 or TabStrip1

Is this the form that gets created when you open a new project via the project wizard?
