I played along to an acoustic version of Sterling Knight playing this song. Here's the video:

The camera shots of the guitar didn't always match up to what he was actually playing, 
I fixed it up by ear. Let me know how it goes when you play it! =)

Here are the chords I used:
Cm - x35543
Eb5 - x68866
Bb - 688766
Ab - 466544
