I'm creating a model to simulate an ophtalmologic clinic, in which users wait, then register, then proceed to be attended by their doctor depending on their condition. I have created 4 different tracks for a wide range of PCIs, but when I run the model, patients don't move past my Patient Arrivals Area (named Entrada1 and Entrada2 in this model). When running the model, I receive an exception error, which I believe is what is keeps the patients from following their track. Any help would be greatly aprecciated.
