Animation not playing with tool equipped?

Hello there. I'm having troubles playing an animation I've created for a tool. I believe the problem is the holding animation overrides my animation? I've tried setting my animation's priority to "Action", however it did not fix anything. I've also created a script that stops all other animations before playing it, but it has proven to be more problematic, if anything. If it is helpful, here is the script, inside of the tool:

animations = {"rbxassetid://129967390","rbxassetid://3294241860"}
animation = Instance.new("Animation")
slash = 0
cooldown = 0
text = script.Parent.Handle.BillboardGui.TextLabel

function repair(contents,name)
	game.ServerStorage.Freeze:Fire(game.Players:FindFirstChild(script.Parent.Parent.Name),0)
	text.BackgroundColor3 = contents[#contents].Value
	for _,v in pairs(script.Parent.Parent.Humanoid:GetPlayingAnimationTracks()) do
		v:Stop()
	end
	animation.AnimationId = animations[2]
	local playanimation = script.Parent.Parent.Humanoid:LoadAnimation(animation)
	playanimation:Play()
	for i = 1,contents[1].Value*10 do
		text.Text = name..": "..(contents[1].Value*10 - i)/10
		wait(0.1)
	end
	game.ServerStorage.Freeze:Fire(game.Players:FindFirstChild(script.Parent.Parent.Name),1)
	text.Visible = false
	script.Parent.Handle.Sound1:Play()
end
