Thanks to you all, I got the code fixed up. If you guys see any issues in the code, please tell me so I can get them patched up as soon as possible.

/*REALLY COOL LIGHTS PROGRAM I2C rev 1.3
------------------------
Evan Grove, Team 2338
released 6/13/2013
rev 0.0: 6/5/2013
This code is used for visual effects on the curved part of the shooter.
During autonomous, LEDs light up in a random pattern. During Teleop, the
lights do a chaser pattern when discs are being fired.

DATA OUTPUTS FROM SIDECAR:
Byte(Bin)       Byte(Dec)        Definition
00000000        0                Autonomous, not shooting
00000001        1                Autonomous, shooting
00000010        2                Teleop, not shooting
00000011        3                Teleop, shooting

ARDUINO UNO I2C CONNECTIONS:
Analog 4 on the arduino is SDA
Analog 5 on the arduino is SCL

DIGITAL SIDECAR I2C CONNECTIONS:
Google it.
Connect analog 0 to a long piece of bare wire. This helps make
the random sequences more random.
