LED blink problem, this programming is not running

/*
  Blink
  Turns on an LED on for one second, then off for one second, repeatedly.
 
  This example code is in the public domain.
 */
 
// Pin 13 has an LED connected on most Arduino boards.
// give it a name:
int led = 13;

// the setup routine runs once when you press reset:
void setup() {                
  // initialize the digital pin as an output.
  pinMode(led, OUTPUT);     
}

// the loop routine runs over and over again forever:
void loop() {
  digitalWrite(led, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(1000);               // wait for a second
  digitalWrite(led, LOW);    // turn the LED off by making the voltage LOW
  delay(1000);               // wait for a second
}

Going to need more information than that, as its not the code since that is straight from the example.

Do you get any messages when the code is compiled and uploaded ?
What does the LED do, if anything ?
What Arduino are you using ?
Have you got an external LED connected or are you watching the one built into a board like the UNO ?

Swap the digitalWrite for Serial.print and use the serial monitor, or try a different pin for the LED.
