Script for changing idle tracks, and walk tracks don’t work

Help and Feedback Scripting Support

  1. What do you want to achieve?
    Making a knife grab game where if you grab a player you hold them hotstage, and when u stop walking or walk with them, its a different animation than the one when you don’t have anyone hostage.
  2. What is the issue?
    The issue is, when i grab a player, and while walking i press MouseButton2 (Which is supposed to let go of the player) or i press MouseButton1 (while holding a player, its supposed to kill him) , the animation doesn’t stop and you still have the “HoldingWalk” and “HoldingIdle” set as your animaiton for walking and idleing; Video Of The Issue
  3. What solutions have you tried so far?
    Tried using for i loops to get all anims track, and if they match the name, i stop them. But that doesnt seem to be working.

The Player.Stat is just a stat i change upon grabbing / letting go or killing the player, upon grabbing its set to “Grabbed”, on letting go or killing i set it to None, and thats how i change the animationTrack

local function oncharacteradded(character)

	for _,v in pairs(events) do
		v:Disconnect()
	end

	events = {}

	local humanoid:Humanoid = character:WaitForChild("Humanoid")

	local char = character

	local styleValue = Player.Stat.Value
	
	local walkanim =  RepStorage.Animations.Walk
	local idleanim =  RepStorage.Animations.Idle 
	
	table.insert(events,Player.Stat.Changed:Connect(function(a) 
		local walkanim2 = RepStorage.Animations.WalkHold 
		local idleanim2 =  RepStorage.Animations.HoldIdle
		
		if a == "None" then
			for i, v in ipairs(humanoid.Animator:GetPlayingAnimationTracks()) do
				if v.Animation.Name == "HoldIdle" then
					v:Stop()
					
					walkanim2 = RepStorage.Animations.Walk
					idleanim2 = RepStorage.Animations.Idle
				end
			end
		end	
		idletrack = humanoid.Animator:LoadAnimation(idleanim2)
		walktrack = humanoid.Animator:LoadAnimation(walkanim2)

		if not walktrack.IsPlaying then
			for i,v in pairs(humanoid.Animator:GetPlayingAnimationTracks()) do
				if v.Animation.Name == "Idle" then
					v:Stop()
				end
			end
			idletrack:Play()

		if not idletrack.IsPlaying then
			for i,v in pairs(humanoid.Animator:GetPlayingAnimationTracks()) do
				if v.Animation.Name == "Walk" then
					v:Stop()
				end
			end
			walktrack:Play()
		end
		
	end))
	
	walktrack = humanoid.Animator:LoadAnimation(walkanim)
	idletrack = humanoid.Animator:LoadAnimation(idleanim)

	if humanoid.MoveDirection.Magnitude <=0 then
		idletrack:Play()
	end

	table.insert(events,humanoid.Running:Connect(function(speed)
		if humanoid.WalkSpeed < 20 and speed > 1 then
			
			idletrack:Stop()

				walktrack:Play()
				walktrack:AdjustSpeed(1)
