Sliding menu help

I am currently using your handy sliding menu tutorial (http://www.kirupa.com/developer/flash8/slidingMenu.htm) and am trying to get a button WITHIN the content area to have the same effect as the main button in the main menu would have - ie slide the content area to the specified content area.

see below for noob script action - (obviously not included rest of script, just the bit i’ve added - rest is exactly the same as the tutorial)

_root.contentHold.content1.b7.onRelease = function() {
menuSlide(contentHold.content5);

};

not even certain if this part of the script that needs to be altered - any help would be appreciated.
