Movement Replication Issue

Replication failing on server and Multi casting. Anim BP working client side only. How can I fix this. I had different char classes with different abilities.

How can I fix this. Please help

Replication is only Server → Client. Variables set on clients will not replicate to server.

Thanks for your reply and time.

I have fixed it. As you mentioned server client based have no issues. I made mistake in Anim BP
