Montage won't play in BP

Hey all, I would love some help. I’ve been trying to iron out why my animation montage isn’t playing, and I’m at my wit’s end. I’ve set up slots, have the montage set to the appropriate slot that’s in the animation BP, and I have my character set to use the animation BP. When checking the BP during runtime, it shows that no progression is happening past the play montage node. No completion, no interrupts, nothing. Any advice would be greatly appreciated.

SOLVED: I was using a marketplace animation (one of the free packs), and the skeletons weren’t compatible. I retargeted the animation, and all is working now.
