It was running fine, and then we heard a clicking sound and it just quit, now it will not start

Make sure battery has a full charge and battery connections all good. You can't do any testing if battery is down. Forget the jumping. Also, check your charging system.
Does starter motor crank? If not, check wiring circuits for the starter motor. Any testing at the starter, make sure tranny is in park or neutral and functional parking brake is set, Safety is your responsibility.
If you have a digital multimeter, you can do some testing. If the battery is down, put a charger on it.
Sometimes if battery voltage is lost, it can effect your security system. I haven't looked to see if it will effect your starter motor?
