Mathcad help: "The forms of these values must match" error

[markus.sparti]

1. The problem statement, all variables and given/known data
I am getting an error, when I assign a value to 'num', stating:

The forms of these values must match
This value has the form: Unitless,
but others have the form: f(any1, [unitless]) => [unitless]

I cannot figure out what the program wants me to do, how do I make the value of 'num := 100' match the others, or vise-versa? I am completely stuck. :uhh:


2. Relevant equations

3. The attempt at a solution
I have tried everything I can think of, I have double checked all the numbers and units and can't find anything wrong. Any help in the right direction is greatly appreciated.

Thanks! :approve:
