GSM SIM900 DATA LOGGER

Hi,
I want to send the data through sim900 using arduino, to my google spreed sheet , am using the following code, But i can't get the data to my google spreadsheet, following is the code, please help me...

#include "SIM900.h"
#include <SoftwareSerial.h>
#include "inetGSM.h"
//#include "sms.h"
//#include "call.h"

//To change pins for Software Serial, use the two lines in GSM.cpp.

//GSM Shield for Arduino
//www.open-electronics.org
//this code is based on the example of Arduino Labs.

//Simple sketch to start a connection as client.

InetGSM inet;
//CallGSM call;
//SMSGSM sms;

char msg[50];
int numdata;
char inSerial[50];
int i=0;
boolean started=false;

void setup()
{
//Serial connection.
Serial.begin(9600);
Serial.println("GSM Shield testing.");
//Start configuration of shield with baudrate.
//For http uses is raccomanded to use 4800 or slower.
if (gsm.begin(2400)) {
Serial.println("\nstatus=READY");
started=true;
} else Serial.println("\nstatus=IDLE");

if(started) {
//GPRS attach, put in order APN, username and password.
//If no needed auth let them blank.
if (inet.attachGPRS("airtelgprs.com", "", ""))
Serial.println("status=ATTACHED");
else Serial.println("status=ERROR");
delay(1000);

//Read IP address.
gsm.SimpleWriteln("AT+CIFSR");
delay(5000);
//Read until serial buffer is empty.
gsm.WhileSimpleRead();

//TCP Client GET, send a GET request to the server and
//save the reply.
numdata=inet.httpGET("www.google.com", 80, "/", msg, 50);
//Print the results.
Serial.println("\nNumber of data received:");
Serial.println(numdata);
Serial.println("\nData received:");
Serial.println(msg);
}
};

void loop()
{
//Read for new byte on serial hardware,
//and write them on NewSoftSerial.
serialhwread();
//Read for new byte on NewSoftSerial.
serialswread();
};

void serialhwread()
{
i=0;
if (Serial.available() > 0) {
while (Serial.available() > 0) {
inSerial=(Serial.read());
delay(10);
i++;
}

inSerial='\0';
if(!strcmp(inSerial,"/END")) {
Serial.println("_");
inSerial[0]=0x1a;
inSerial[1]='\0';
gsm.SimpleWriteln(inSerial);
}
//Send a saved AT command using serial port.
if(!strcmp(inSerial,"TEST")) {
Serial.println("SIGNAL QUALITY");
gsm.SimpleWriteln("AT+CSQ");
}
//Read last message saved.
if(!strcmp(inSerial,"MSG")) {
Serial.println(msg);
} else {
Serial.println(inSerial);
gsm.SimpleWriteln(inSerial);
}
inSerial[0]='\0';
}
}

void serialswread()
{
gsm.SimpleRead();
}


what i have to change in this section"numdata=inet.httpGET("www.google.com", 80, "/", msg, 50);"
