Changing Coordinate system using weak form PDE

I'm using the Weak form PDE tool. I'm trying to sole a problem in 2D Polar Coordinate System. I have rewritten my problem in this coordinates system and under "Definition" I have selected the Cylindrical System. So the independent variables should be "r" and "phi". But comes out this error:
"Undefined variable.
- Variable: r
- Geometry: geom1
- Domain: 1
- Feature: Time-Dependent Solver 1 (sol1/t1)"
I think it comes out from the weak form of the PDE equations which are written using r and phi as variable.
Why it doesn't recognizes r and phi as variable?
Thanks in advance.
