Help What am I doing wrong? Matrix Led
Unfortunately I think you are missing the actual error message and have just copied the result.  I suspect if you scroll back up through the output it will say loop is missing.

All Arduino sketches (well almost all) have to have setup() and loop() functions.  The underlying 'stuff' will call setup() once and loop() repeatedly.  

I hate global variables, but in this case I would be tempted to move those arrays out of the function and make the constant global values.  That way they will be in memory as the Arduino boots and you won't have to waste processor cycles setting them up.

It may be a silly question, but are you using the right hardware?  This might help check that http://playground.arduino.cc/Main/LedControl
