A better connection would be to have the COMMON of your switch going to Vss (0v), with either side to your PIC pins as before. You then only need a SINGLE Pull-UP resistor on each pin going to +5v. 10K is a good value.

On the switch its three prong. The middle prong is going to ground. The one side of it is going to PORTB.5 and the other side is going towards PORTB.7. You said put a Pull-UP resisor on the ones going to PORTB.5 and PORTB.7. That makes sense, but you said going to +5v? I don't understand that... Can you please clairfy, thanks.
