    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);"
