To learn Prolog and logic based programming in school, I've been trying write a basic Expert System that takes a bunch of symtoms that the user may have and from there outputs one of 4 (or 5 if it is unable to find one) conditions. I've sort of understood the system where the user determines the arguments (instead of writing them right into the trace call). But honestly, I'm so unfamiliar with SWI-Prolog that I can't figure out what I did wrong in this program.

I'm not getting errors with my code, which leads me to believe I did something right - but I can't get it to work. Prolog crashes whenever I try to run the trace, it goes through a few steps and then once arriving at the headache portion asks me whether I have the symptom.

No matter what I do it exits right there. Could I get some leads on how to get this at a workable state?%Disease Identification Game%Start with?- go.
