I have 3 screens, the title screen, the main screen, and a screen after that. On the last screen. I have a button that goes to the main screen. However, when I press the button I want it to not only navigate to the main screen I also want it to do an action on the main screen. However, I don’t want the action to happen when you first open it from the title screen. So basically make a button on the other screen affect the main screen. I know there is a thing called’broadcast message’ in scratch which means when it broadcasts you can make an action on any screen. Im wondering if there is something like that in thunkable. ty ---

Use a app variable. For example: - ## Title Screen: Initialize app variable btnVar to “0” If btnVar = 1 new image code - ## Last Screen When button pressed set btnVar to “1” ---
