Animation won't stop, and I dpon't understand it?

Hello, I have made a ground-pound animation that is stopped by another animation, if you touch the brick. But the animation won't stop, can someone help me create a part that stops animations?

There is no code included because i really didn't have a code, except for the "press e to ground pound script"

Thanks if you could help I'd really apperciate that. -Theroofypidgeot
