calling variables by using tags

I'm trying to reproduce the COMSOL tutorial "Two phase flow in column" by using Richards' law physic interface instead of Darcy's law. I'm having problems in calling the variable kr (relative permeability). This variable is calculated by the physic interface. When I write dl.kr, the program gives me this error:
Undefined variable.
- Variable: kr
- Geometry: geom1
- Domain: 2
Failed to evaluate Jacobian of expression.
- Expression: dvol*(comp1.dl.v*comp1.dl.rho)
Failed to evaluate Jacobian of expression.
- Expression: (comp1.dl.rho*(comp1.dl.u*test(comp1.p_wx)+comp1.dl.v*test(comp1.p_wy)))*(dvol)
I've tried to write this variable in different ways, such as:
root.comp1.dl.kr
comp1.dl.kr
From the Subsurface flow module user guide it seems that these are correct. Anyway, it doesn't work.
Any idea of the problem?
Thank you
Giulia
