moving MClip smoothly using Actionscript

[dptoot]

I have a menu with a box that surrounds the menu text for the selected link. I have it so that each time a link is pressed the box (a sperate MC) is moved to surround the appropriate menu text (i.e. which one was pressed. This was done by using

this.contactPage.onRelease = function{
menuBox._y = 320;
}

and etc. for each menu btn. The problem is that when it moves to the place it does it instantaeously where as I would like it to slide smoothly from its present position to the preset position (e.g. _y = 320). Is there a way to do this with actionscript? Thanks in advance masters of Flash!

ON the box MC.........

onClipEvent(enterFrame){
this._y+=(_root.ypos-this._y)/7;
}

...and code for the button

_root.ypos=320;
