Flow rate determination in 3-D

I am working on 3-D laminar flow with time dependent via rectangle geometry.
The Comsol version involved is Comsol 3.5.
I had refer some previous forum which discussed vividly about the technique to find out flow rate over the 3-D surface by using spf.U.

www.comsol.co.in/community/forums/general/thread/25967/
However, when I try out in my Comsol 3.5, under physics > Global Equations.
It pops out the error of:
Error: 9171
Syntax error in expression
-Expression: spf.u
-variable: E
Any advice for this? Or spf.U is not meant for Comsol 3.5?
Thanks and appreciate.
