Problems with IR Sensor with Temperature Sensor, LCD, and LED

Projects Programming
1

Okay so I'm new to programming and I'm trying to get an Ir Sensor to toggles between different functions that will display information on an LCD screen. Right now I only have a temperature sensor set up to display information and an LED on other spots just to see if its changing statements.

I cant find a way to consistently update the LCD with the Temperature readings without having to press the button on my remote to update it. I know my code is ruff, but I'd appreciate all the help I can get.

post your code directly inline. can' read the attachment without download... (and use code tags)

You call the RemoteIR() function, which does NOTHING with a remote IR, only when loop() sees that there is input from the remote. Clearly, that is not what you want, so why do you do it?
