Animation Weight Help

So I have an animation for my sword(idle animation), but I can’t use idle since the default animation will override so I have to use movement or something bigger, but for some reason it does override, but it replaces all other animations like movement etc. How can I fix this?
Thanks for reading.

maybe rename the animation? So roblox studio wouldn’t think, you’re talking about the actual roblox idle animation.

Well I have this animation that when you equip the tool it plays an animation and stops when you unequip it. But, it replaces animations that should be playing like movement and etc. So I need help because if I choose idle than it doesn’t correctly function, but if I put movement it replaces any movement.
