Hey Outpost!
You can achieve a up and down forever effect a couple ways. You are adding 1 to Bar1State every time the button is pressed, so once it hits 10, it keeps going and doesn't trigger the if or else if for resizing. You'll need to set it back to 0 once it is out of range so it goes through the resizing again.
Add this block into your else inside the on activate of button block and you should be good to go.
