Tnks for a reply!
But this is my solution:
In this moment i have 2 Layouts. First Layout with "Start" Button and the second Layout with game engine.
Layout Home
LocalStorage --> Check Item "Total_Coins" Exist
LocalStorage --> On Item "Total_Coins" Missing
Dictionary --> Add Key Get_Total_Coins with value 0
LocalStorage --> Set Item "Total_Coins" to 0
LocalStorage --> On Item "Total_Coins" Exists
LocalStorage --> Get Item "Total_Coins"
Dictionary --> Add Key Get_Total_Coins with valueLocalStorage.ItemValue
Layout Game
Global number Coins = 100
Global number Get_Total_Coins = 0
LocalStorage --> Check Item "Total_Coins" Exist
LocalStorage --> On Item "Total_Coins" Exists
Set Get_Total_Coins to Dictionary("Total_Coins")
Set Get_Total_Coins to Get_Total_Coins + Coins
LocalStorage --> Set Item "Total_Coins" to Get_Total_Coins
