I made a button move a ball( I called this ball a bullet) to a certain location and made it move forwards when a timer was called, but when I do this MIT App Inventor crashes. What do I do?

I made it so that when I click a button, the ball moves to where the imageSprite is and then a timer is enabled so that when the timer fires, the ball moves forward on the canvas a certain amount of pixels. Also make sure your imageSprite Y or X is not on the edge or else the app is likely to crash.
