Deffinition of variables

Hope you are going well.
Actually I decide to define velocity in the spherical coordinates. After selection this coordinate from definition section, I createt two equations for velocity in r and theta directions in variable section as:
Vr= (0.06*(1-1.5*(0.001/r)+0.5*((0.001/r)^3))*cos(theta))*(r>0.001)
Vtheta= (0.06*(-1+0.75*(0.001/r)+0.25*((0.001/r)^3))*sin(theta))*(r>0.001)
After that in "Transport Diluted species" in subsection "Convection and Diffusion", I selected spherical coordinate system and add Vr and Vtheta as velocities in r and theta directions.
However after running, the below error showed:
Failed to evaluate variable Jacobian.
- Variable: Vtheta
- Geometry: 1
- Domain: 1
I don`t know what I have to do?
I will be thankful if you help me.
Thanks a lot.
