turbulo is on a distinguished road

I'm fairly new to OpenFOAM and would like to know if it possible to use the gradient operator to define a new boundary condition for velocity. When I use
the compiler says:

 'grad' is not a member of 'Foam::fvc'
There seems to be no other issue with the code if I remove the part involving the gradient.

I've taken the already existing movingWallVelocity BC and modified it to get the new BC. I'm fairly good at C++ but still not familiar enough with OpenFOAM's structure to figure this out. Any help or hint in the right direction would be really appreciated.
