Dynamic block problem

I am trying to create a window block that stretches both mullions horizontally and vertically. I figured out how to get both to stretch horizontally but when I try to stretch vertically I get a really funky skew thing happening. Could someone look at it and tell me what I am doing wrong? Thanks!

I think I figured this problem out. I am pretty new at dynamic blocks and I realized that the chain affects the parameters not the actions and I did not need the actions to be linked.
