Just “Set Visibility → False” in its place and then you can execute the rest of the code! Then you can put that at the end.
Okay I think I see the big thing. It looks like you need to take the “TimerCount” Set timer by Function Name off of begin play on your GM. Because it’s starting when the game mode starts existing, which is BeginPlay. Give it it’s own Custom event instead of begin play, that the main menu widget will call on, on that button press, before the widget gets removed.
Then, It looks like it’s set up right… I think.
Change that and let me know what happens!
