Mathcad: forms of values do not match?

[markus.sparti]

I am looking for any help I can get, I have been working on this for hours and cannot figure it out. Should I include more info in my post?

I am getting an error stating:

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

when I assign a value to 'num'

I am new to Mathcad and I am not sure what this error is trying to tell me. I have tried changing the value of 'num' but I am still getting the error, any ideas?

Here is what I'm working with:

Any help is greatly appreciated, thanks!

Yes, including more information in your post would be helpful for others to understand the problem and provide assistance. Can you provide more context on what you are trying to achieve with the code and what values you have assigned to 'num'? Additionally, it would be helpful if you could provide the full code or a screenshot of the error message. Without more information, it is difficult to provide specific guidance on how to resolve the error.
