Solve Block With 9 Row Vector Problem

Hello guys,

I am new to this forum and this is my first post. I would appreciate input from others regarding my problem. Maybe I did a stupid mistake so please excuse that.

In the picture you can see that I assigned all the Units regarding my Problem that I want to solve for, but nevertheless, mathcad tells me they are not compatible.

In future, please attach your sheet unless you have a compelling reason not to.

Because it was short, and because it looked interesting, I started duplicating (attached), and got as far as the second line:

I "solved" for r--the yellow box--to make things work, but what else is missing?

Oh sorry yeah on the first page I assigned r:=30cm which is actually r_w.

I corrected that and here is my sheet!

Solution (in Express, so without a solve block) attached. How did I do?
