Serious problem with function evaluation in Mathcad?

[PCES]

Hello all,

I have defined a function in Mathcad (prime v6.0) to calculate elastic modulus of concrete with two parameters density (gama-c) and compressive strength (fc) as shown in the following photo. As you can also see from the photo, the function gives a different value and units to that if we evaluate the expression directly.

I added the mcdx file for your reference. 

I am looking toward to hearing from all of you.

Thank you!

I have tried with new version of prime (v7). The problem still persists

Thank you. It was my mistake but not Mathcad issue.
