The output I get is when I push any of the button's our Alarm and Fan LED's turn on. What I need is that only when gas, RB.6 is high the Alarm and Fan LED's turn on. If RB.6 is high and RB.5 or RB.4 are high, my Alarm and Fan LED's should turn off.

Just add the bit together like this: temp3 = Flow + Temp temp3 = temp3 + Gas ' temp3 can ONLY be 3 if Flow=1, Temp=1, and Gas=1 alarm dang level rising IF temp3 = 3 THEN ' whatever ENDIF Keep working on it, and keep posting.
