In addition to the reference for learning about scope posted in Reply #3, here's a reference for properly asking a question and posting your code: Read this before posting a programming question .... In particular, scroll down to Item #6. As the name implies, you should have read this before posting.

Hi. Maybe you can change your code like this.

int led1 = 11;
int led2 = 12; 
int led3 = 13;

void setup() 
{
  pinMode(led1, OUTPUT);
  pinMode(led2, OUTPUT);
  pinMode(led3, OUTPUT);
}

 void loop () {
  digitalWrite(led1, HIGH);
  delay(1000);
  digitalWrite(led1, LOW);
  delay(1000);

  digitalWrite(led2, HIGH);
  delay(1000);
  digitalWrite(led2, LOW);
  delay(1000);

  digitalWrite(led3, HIGH);
  delay(1000);
  digitalWrite(led3, LOW);
  delay(1000);
 }
