positioning a movieclip relative to another movieclip
===

I have two movie clips on the stage and what I'm trying to do is position the second mc relative to the left of the other (the first one's width is 24px, while the second one is 151px)

I thought the way to do this was by giving the second mc the x of the first then subtracting the width from the second mc x, but it doesn't seem to be working. how does as3 calculate x positioning of an mc? is it from the center of the mc out or is it using the origin point somehow?
