Link parameter value to a dimension

I have an elevation drawing of a door that I am going to make parametric so it will update if I change things like top rail width, or stile width.

Along with the door elevation, I also have section drawings of that door. The sections are not parametric, just standard blocks and polylines.

Now, what I'm wanting to know is can I somehow link a value from the parametric block to the value of a dimension on the section drawings so that if I were to stretch the top rail in the section from 4 5/8" to 5", the top rail on the elevation would change with it?

Yes - try d2 = d1 for your dimensions to be the same
