Error circular variable dependency detected

Hello, I'm simulating a piezoelectric ring on COMSOL 4.3a and I'm calculated impedance of the motor, my method is to use "Frequency domain"
impedence = V/I
I = mod1.intop1(intcpl_source_i) (variables in Global Definitions) , intop1 is integration in Definitions
intcpl_source_i = -imag(ampz3d.nJ) (variable in Definitions)
but when calculating the current through the surface of the ring, the error appears:
Evaluation of resultat expresion detected
-variable : mod1.smpz3d.Jy
-Geometry : 1
-Domain :1

I don't understand why ? you can help me ?
