Hello everyone. I am frustrating with this problem. I was trying to define a variable 'FPtA' with a symbolic function and then evaluate the 'FPtA'. However, Mathcad kept saying one of my variables was undefined. Details are shown in the snapshots and the attached mathcad file. Could anyone help me with it?

In your function definition, the right-hand side contains an apw and an hpw, the left-hand side doesn't! If you replace the ap in the LHS by apw, and replace the hpw on the RHS by apw (this might or might not be the right thing to do - only you will know) then it works ok.
