Yea I got it What I did was that I created a global variable "LevelNumber".
-"Game" Layout
System->Set "LevelNumber" 0
System->Set "Score" 0
I kept the "when fail go to "start"
System->Score=50->Add 1 to LevelNumber
-"Start" Layout
System->On start of layout->Add 1 to "LevelNumber"
System->LevelNumber=2 ->Go to "Last Layout"
