I have written code that generates geometry and assigns materials to all of the geometry I am working with but every time that I execute the code and then press the compute button in my app I keep getting an error that 'epsilonr' is not defined. I have tried specifying the values for each material within the code and that hasn't worked either. I have attached the file I am working on.

I took just a quick look at your model. You assigned gold as a material to some surfaces, but its default material properties didn't include a relative permittivity (which is the epsilonr quantity), but the physics you were/are using apparently needs to know that. You can either define your own materials with appropriate properties or add properties as may be needed to Comsol-defined materials. See attached image, where I added a relative permittivity = 1 (which may or may not be an appropriate value; that's for you to decide) to the gold. Now, I'm not sure if that is the only thing I'd worry about in your model, but it might be at least part of what is causing the message you saw.
ADDED: FYI, the file you attached seem to run ok without generating any error messages, on my computer. Maybe your issue has something to do with the associated app that you are creating?
