Formatting and code errors?

Hello I have managed to get both the Adafruit Datalogging shield walk-through and this individual code working http://www.learn.parallax.com/reed-switch-arduino-demo separately, but trying to combine the two together I get these errors. I think I have it all arranged correctly but any help would be greatly appreciated. Board Arduino Uno and Adafruit Datalogger shield.
