How to define a convection-diffusion Term in to different subdomains?

Dear all;
I am trying to model a fractured porous media to investigate solvent diffusion from fracture into the matrix. To do so, I have already developed a 2D geometry composed of two rectangulars, i.e. geom1 and geom2. There is a term in the model used to account for mass transfer between fracture and matrix; I mean:
R=k*(CF1-CM1) (kindly please find the attached file);
Running the solver; COMSOL generates an error massage "can not evaluate CM1". I think it is due to the coupling nature of this type of equation.
Can anyone help me in this regard?
Your kind contribution is highly appreciated in advance;
