Scrollbutton to Scroll movieclip

Hi everyone,

I’ve got a small problem here, and I’m relatively new to AS, so bear with me.

I have a movieclip with a list of option in it. The list is too long to fit in the space provided, so I’ve masked it, and created a scroll button on the side. The list changes often and is not a fixed length.

I can make the scroll button drag up and down just fine, but I can’t get the movieclip list to move with it. All the tutorials I find online are showing only text with the scroll option, not moving an actual movieclip.

I’ve attached an image of what I’m trying to do, so you can see it.

Thanks in advance,
