Character Sound System Failing

I had created a footstep sound system for my first-person character in my current project, but because I didn’t need the arms to be visible I just deleted them from the character’s BP. Apparently the animation I made my sound system off of depended on that, because now the footstep sound system doesn’t work. I don’t know how to fix this and can’t seem to find any help anywhere on the subject. Please help if you can. Thanks.
