Please help,

I keep running into this same problem with my if statements and have not been able to find the reason why. Any help is greatly appreciated.

Thank you

You'd have a LOT less code if you read the three switches ONE time on each pass through loop() and put the one bit value you read into a different bit in a byte, and used a switch statement with that byte as the switch value.
