My projectile duplicates on my client, and the Health variable gets subtracted twice, but when shot on server the projectile works fine

I managed to fix it! I set it back to how it originally was, and in the Cast and Decrease macro I just put a switch has authority between the input and the Set Health so only the Server side sets the Variable not the client as well. Thanks for the help
