Morse Code With for loop help needed

Using Arduino LEDs and Multiplexing

int GreenLED = 12;   
int RedLED = 11; 

void setup()                      
{
 pinMode(GreenLED, OUTPUT);
 pinMode(RedLED, OUTPUT);
}


void loop()
{
int times; 
for(int i=0; i<times; ++i)
{
  dash(1); dot(2); blank(1); //D
  dot(1); dash(1); blank(1); //A
  dash(1); dot(1); blank(1); //N
  dot(2); blank(1); //I
  dot(1); blank(1); //E
  dot(1); dash(1); dot(2); blank(1); //L 
return times;
}
}
 

int dash(int times) {
    digitalWrite(GreenLED, HIGH);
    delay(750);  
    digitalWrite(GreenLED, LOW);   
    delay(750);
    return(times);
}

int dot(int times){ 
    digitalWrite(RedLED, HIGH);   
    delay(250);                    
    digitalWrite(RedLED, LOW);   
    delay(250);
    return(times);
}

int blank(int times) {
    digitalWrite(GreenLED, LOW);
    digitalWrite(RedLED, LOW);
    delay(1000);
    return(times);
}

I don't know how to use the numbers in the brackets after specific commands.
The program verifies but the specified LED's don't even light up.
If somebody could help me it would be a great help?
