Playable character animation error when playing level in editor

hi,

ive been coding my playable character using the guidance of this [webpage][1] . I have completed it and tested it in play view in the editor but it came up with these errors

and my gun doesnt show up on the model which i originally connected with a socket.

I’ve got the gun on my character now but, when I move, it keeps aiming the gun and the view angle changes to the chest of the character as well as moving sideways instead of walking etc. The error codes above are part of the coding with the rifle hip animations and referring to the webpage linked above, there is nothing I’ve done different. I need help,ASAP since I have a deadline on Friday.
