Use of coefficient form PDE with global equation (simple ODE)

I am trying to solve a coefficient form PDE "dC/dt+ u.dC/dz =D 1/r.d/dt (1/r.(dC/dr)" with a global ODE equation "dCt/dt=constant*(C(t,L) - Ct)" together. I am using 4.1 version so I know that I can not use C(t,L) with ODE so I replaced it with aveop1(C) which is the average operator for C at the location of L. But I am getting a zero answer across the geometry. Could you please someone help me?
