Help with animations!!!

I need help , I have my "1" key set to the Draw Dagger animation, I just need to know how to actually get the dagger out and replace the staff , the pack I have came with this script which are attached to the weapons (see photo) themselves the staff is equipped default, and the mesh renderer on the dagger is unchecked by default but equipped it would be nice to be able to cycle through the weapons with my scroll on my mouse and eventually be able to pick up weapons etc
