what else do i need to change from this code shown below, in order to upload 2 variable to xively?

int thisLength = 8 + getLength(thisData); <---- sending one data 8bytes,
so for 16 bytes: int thisLength = 16 + getLength(thisData)++ getLength(thisData); <--- am i correct?

void sendData(int thisData)
{
  // if there's a successful connection:
  if (client.connect(server, 80))
  {
    Serial.println("connecting...");
    
    // send the HTTP PUT request:
    client.print("PUT /v2/feeds/");
    client.print(FEEDID);
    client.println(".csv HTTP/1.1");
    client.println("Host: api.xively.com");
    client.print("X-ApiKey: ");
    client.println(APIKEY);
    client.print("User-Agent: ");
    client.println(USERAGENT);
    client.print("Content-Length: ");

    // calculate the length of the sensor reading in bytes:
    // 8 bytes for "sensor1," + number of digits of the data:
    int thisLength = 8 + getLength(thisData); 
    client.println(thisLength);

    // last pieces of the HTTP PUT request:
    client.println("Content-Type: text/csv");
    client.println("Connection: close");
    client.println();
    
    // here's the actual content of the PUT request:
    client.print("sensor1,");
    client.println(thisData); 

   client.print("sensor2,"); 
   client.println(thisData); <----- add one more variable to this data
  } 
  else
  {
    // if you couldn't make a connection:
    Serial.println("connection failed");
    Serial.println();
    Serial.println("disconnecting.");
    client.stop();
  }
  // note the time that the connection was made or attempted
  lastConnectionTime = millis();
}
