PING Sensor Code Not Working [SOLVED]

I am trying to get an HC-SR04 Ultrasonic Ping Sensor working. The sample code I have tried from a couple of sites throws errors that I don’t know how to fix. Does anyone have sample code to get one of these working with the Core? I started here: https://code.google.com/p/arduino-new-ping/ Thanks in advance!
