error in script

Im following the 3d platform tutorial and am having a hard time with a particular script that i have typed exactly as it is in the tutorial.

If (isLoading)
{
GUI.Label (Rect((Screen.width/2)-110, (Screen.height/2) - 60, 400, 70),
“Loading…”,“mainMenuTitle”);
}

I keep getting Assets/Scripts/StartMenuGUI.js(45,54): BCE0044: expecting :, found ‘;’.

Try putting ‘new’ in front of Rect

I realized the error i was making i had left out

function Update(){}
