thanks For this Big Help

Also is good to explain WHY that doesn’t work. In a variable initialization (when the app starts creating the variables), makes no sense to assign the value of a variable that may not exist yet to another variable. That’s why the solution @George_Loungos gave you works, because at that point (Screen1.Initialize) all the variables has been created and is safe to use them and their content.
