Coding Layers

All,

Is there a piece of code that will make always make an object the top layer? I have a three types of buttons on two layers (about 15 in one, 4 in the other) and a banner comes up when you roll over them. The banner will cover some of the buttons, but be overlapped by others. I want the banner to completely cover all buttons during the roll over.

This is my .swf:
