Help with depth

Hi i hope u can help me cause i know u rock!!

I´m building a form applicaton using components, i have tree separated forms every one of them inside a MovieClip and i call them whenever i need with the tab component, ok?

Now i also build a slide menu to access any part of the form in the left part of my movie and when it appears it is alway shown at the back of my forms.

I can´t make my menu to be in front of the forms, i have already tryied by inserting the menu on a higher level form, in a higher layer…I want to know if there is an action that helps me to tell the menu to have a higher depth when its shown.

In a very more simple way, How do i manage MovieClips depth ? , because components inside my forms always superpose to my menu.

How do i disable my form’s movieclip when the menu is shown.

Thank u and sorry about my english.
