Error pickup item

Well, I was watching jonas molgard’s tutorial about changing from third to first person, but after I finished watching the tutorial, I had a problem, the character picks up the weapon and performs the animation to pick it up and trick it however when it will stand in idle position with the rifle, the animation comes back as if it had nothing on hand, could someone help me (before I work on the tutorial was normal)
