UCE0001: ';' expected. Insert a semicolon at the end."

Hey guys

I'm trying to adjust the size of the text on my screen for my HSC major work but keep getting this error message

"Assets/Script/Menu Character.js(10,17): UCE0001: ';' expected. Insert a semicolon at the end."

here is the code that i sourced from a unity help forum

  function OnGUI    ()    {
            GUIStyle myStyle = new GUIStyle(GUI.label);
                myStyle.fontSize = 50;
           GUI.Label(Rect(0,0,Screen.width,Screen.height),"W = Walk Forward\nS = Walk Backwards\nA = turn left\nD = Turn Right" ,myStyle);
     }

The line noted by unity as needing a ; at the end already has one. "GUIStyle myStyle = new GUIStyle(GUI.Label);"

any help regarding this error in my code would be much appreciated =) Thanks
