This its vexing me, hope someone can point out where I’m going wrong.

Here’s a pic of a wall I’m trying to create as a dynamic component. What I’m trying to accomplish is to be able to scale the wall either in height or length and have everything adjust correctly.

Here are my formulas to position the “TopPlate” and “DblPlate” relative to the vertical length of the ply component of the wall; except for the dimension to adjust from the top of that ply length, the formulas are identical

I created the “plate” components at the same time, in the same axis. And, I don’t know what the “red # error” is. I’m trying other formulas in other fields now, to try to get the proper results.
