This places the frame 1000 “screens” downwards. So the frame has to travel so much in that 3 seconds, that you don’t see it, because it has to move so fast. I suggest you only move it down by a few pixels, so it’s smoother and more responsive
You should change it to the smallest number possible, like 1.25 (just make sure it disappears completely).
If you want the message to stay on the screen for longer, try changing the wait(3) to a bigger number. The tween’s duration is 3 seconds, and if you wait 3 seconds after starting it, the second tween will start exactly when the first ends. If you wait 5 seconds after the first tween, the frame will stay there for 2 seconds before disappearing.
