MathCad Variable Undefined (even though I just defined it)

Question

Hoping to run into some mathcadders:

I have a worksheet which includes the following except (and error)

Any help?

Answer 1

Mathcad "reads" down and right and you have defined the equation above the variable definition. If you drag the equation down it will work.
