I'm still very new to arduino and coding and having some difficulties trying to figure out what I am doing wrong here. 

This program is to have control over 2 relays, using a combination of an IR receiver and a ir\_remotecontrol with pre-programmed buttons (ir\_remote buttons 1 = relay 1 toggle, button 2 = relay 2 toggle). 
A master momentary hard wired switch to override changes to the relays and toggle their states i.e if both relays are on via ir remote - toggle them off, or if only 1 relay is on toggle it off with 
first click of button then toggle both back on after second click of button. 
The Bluetooth module and android app is to also control relays the same as the ir\_remote via integers sent through the serial port.

It all sort of works at the moment...

If I just work the relays using the ir remote and the momentary switch it all works perfectly. 

if I make sure the relays are in the off position using the remote switch and then use the Bluetooth it also works perfectly. 

The problem only is when I use a combination of the ir remote or switch and the Bluetooth - things get weird - the Bluetooth commands seem to reverse and the relays start making a buzzing noise and the momentary switch muddles things up so basically it's all bad news! I've stared at this code for hours and tried a few different things but I just can't see what's wrong.

Let me know if I need to give a more detailed example of the errors I am having. Just thinking it is probably obvious for you pro's out there when you see my noob code!. 

Any help would be greatly appreciated!
