Adjusting a mc's height with a slider

I’ve been racking my brain all day trying to figure this out… I’m not the best when it comes to actionscripting…

I have a sound loop that plays perfectly and I have a volume slider that works great. Here’s my problem, I need to control a seperate movie clip -an animation- with that same slider (the volume controller)… It needs to adjust the height of this mc up and down… like when the volume goes down, the height of the seperate mc gets smaller and vise/versa…

any ideas?? this seems like a fairly straightforward thing to accomplish, but like I said I’m not all that great at AS… thanks…
