Character Animation Not Playing when Pressing Key

So, I’m having some trouble with this. I have tried to do it in different ways and nothing works.
The animation I want to play is from idle to holding a weapon.

The character starts in the idle animation then when I pick the weapon I pressed a key to put it into his hand. The problem is that the animation for holding the weapon doesn’t play at all.

These blueprints are inside of the character’s blueprint.

The pick up blueprints work just fine, but as soon as I try to switch from the holster to the hand the animation doesn’t play.

These are the blueprints inside of the the animation blueprints.

This is the animation states.
