Ok, first time I noticed this..
Goto layout by name : ""&LevelCleared does work, but just LevelCleared doesn't..
as i said in the main post , their names are 0 , 1 , 2 , 3 , 4 ... without the default "Layout" thing
and LevelsCleared is 0 by default
But it's working now ( with LevelsPassed and LevelsCleared ), so you don't need to worry
