diffusive_double_layer application not working

Application ID: 21981 seems not be working properly when I tried to simulate on COMSOL 5.0.
I just downloaded it from the application library and tried to follow strictly.Not working!

Undefined variable.
- Variable: cX
- Geometry: geom1
- Domain: 1
Failed to evaluate variable.
- Variable: rho_space
- Defined as: (((cX*zX)+(cA*zA))*F_const)
Failed to evaluate variable.
- Variable: comp1.es.scd1.rhoq
- Defined as: rho_space
Failed to evaluate expression.
- Expression: d((-comp1.es.scd1.rhoq*test(comp1.phi)*comp1.es.d)*(dvol),{test@19})
- Feature: Stationary Solver 1 (sol1/s1)


Is it any error caused because I'm not using 5.2 or was simply my fault in not being that careful in the steps?

Thanks in advance.
Have a lovely day!
Best Regards
Thales Machado

HI

I found two errors. After fixing them the model works.

1. Variable rho_space must be defined under Component, otherwise Comsol does not understand the variables cA or cX.
2. Under transport of Diluted Species the Electric potential variable must not be User defined but Electric potential (es), i.e. takern from the Electrostatics node.
