Multiple DS18B20, read problems

Using Arduino Sensors
5

Not much luck for me today. I used the very simple code below and it wont even detect my sensors if they are both connected. No problem one at a time though.
I've wired my sensors exactly like this: 

#include <OneWire.h>

#include <DallasTemperature.h>


 
// Data wire is plugged into pin 10 on the Arduino
#define ONE_WIRE_BUS 10
 
// Setup a oneWire instance to communicate with any OneWire devices 
// (not just Maxim/Dallas temperature ICs)
OneWire oneWire(ONE_WIRE_BUS);
 
// Pass our oneWire reference to Dallas Temperature.
DallasTemperature sensors(&oneWire);
DeviceAddress tmp_address; 
int numberOfDevices;
void setup(void)
{
  // start serial port
  Serial.begin(9600);
  Serial.println("Looking for sensors...");
  // Start up the library
  sensors.begin();
  delay(6000);

numberOfDevices = sensors.getDeviceCount();
Serial.print("Found ");
Serial.print(numberOfDevices);
Serial.println(" sensors. Starting now...");
}
 
 
void loop(void)
{
  // call sensors.requestTemperatures() to issue a global temperature
  // request to all devices on the bus
  sensors.requestTemperatures(); // Send the command to get temperatures
for(int i=0;i<numberOfDevices; i++)
  {
    Serial.print(i);
    Serial.print(":");
    Serial.println(sensors.getTempCByIndex(i));
    delay(100);
    
  }
  Serial.println();
  delay(1000);
  
 
}
