Help, LCD Display

I changed the code to this:

#include "LiquidCrystal.h"

// initialize the library by providing the nuber of pins to it
LiquidCrystal lcd(8,9,4,5,6,7);

void setup() {
lcd.begin(16,2);
}

void loop() {
  lcd.setCursor(0,1);
  lcd.print("Hello World");
}

I then turned the pot slowly back and forth and nothing happened.
