App Designer: Push-button and keep certain variables in workspace

I am using a push button. When I push it, I get a variable in my workspace. However when the push button function ends, all workspace variables are cleared. How can I store my variable in a safe place to not get cleared when the push button function ends?

Have the function store the data in a property of the app.
