Object reference not set to an instance of an object

I’m really starting to hate these errors i can never work out what is the problem.

Error : NullReferenceException: Object reference not set to an instance of an object
TimerScript.Update () (at Assets/Scripts/TimerScript.cs:58)

levelLabel.text = "Level: " + GameManager.Level;

error with that line ^^
I have tried this

if (GameManager.Level != null) {
			levelLabel.text = "Level: " + GameManager.Level;
		}	

Any help would be great.
Thanks :smiley:

Note the code would be:

   if (GameManager != null) {
        levelLabel.text = "Level: " + GameManager.Level;
    }   

But your problem might also be that ‘levelLabel’ is null.
