Help with a shield

Hey guys
I'm working on a project for my school, and they are really counting on me, so this HAS to work, no matter how
The thing is, I'm working on some sorta floating device that reads the level of a river, and if it's bigger than a preset value, it should send an SMS to a preset number. The problem is that they bought me this SPARKFUN shield: https://www.sparkfun.com/products/9607 and the only base sketch I found for it was one that took a serial message and sent it. After some more researching, I found this: http://www.open-electronics.org/how-to-send-and-receive-sms-with-gsmgprs-gps-shield/ that taught me how to send a preset message, but it was for another shield (http://store.open-electronics.org/Arduino/Shield/GSM_GPRS_GPS_SHIELD). My question is: would the program from the second site work on my shield? Ya know, because it's not meant for it... But it would REALLY help me if it did.
So, if anyone could teach me how to at least create a preset message program for my shield, I'd be really thankful.
Thanks in advance

You say you have found a sketch that reads a string in from the serial port and sends it in an SMS. I assume you have tried it and confirmed it works. So just replace the serial port reading stuff with sending a single hard-coded string, and you're home and dry. You need to take stuff out, not put it in.
