Enabling GSM for Antrax GSM/GPRS shield

Hi,

I am attempting to initialize my Antrax GSM/GPRS shield to send and receive SMS. Below is the modified code without gps, I am having troubles uploading it. The error states: "core.a(main.cpp.o): In function 'main': undefined reference to 'setup', undefined reference to 'loop' ".

Code:

#include <Wire.h>

This is not full code. Any input would be greatly appreciated, thanks!
