Hi! i am modifying a script and i want to know what is wrong with it.. can someone help me?

The script (not mine, credit to: G2_funny)

script.Parent.Activated:Connect(function()
	if script.Parent.Text == "Sprint" then 
		script.Parent.Text = "Walk"
		game.Players.LocalPlayer.Character.Humanoid.WalkSpeed = 30
		game.Players.LocalPlayer.Character["Garbage Bin"].Handle.Transparency = 0
		game.Players.LocalPlayer.Character.Animate.walk.WalkAnim.AnimationId = ('rbxassetid://5529293776')
		game.Players.LocalPlayer.Character.Animate.idle.Animation1.AnimationId = ("rbxassetid://5529293776")
  _G.PlayAnim:Play()
	else
		script.Parent.Text = "Sprint"
		game.Players.LocalPlayer.Character.Humanoid.WalkSpeed = 16
		game.Players.LocalPlayer.Character["Garbage Bin"].Handle.Transparency = 1
		game.Players.LocalPlayer.Character.Animate.idle.Animation1.Character.Animate.walk.WalkAnim.AnimationId = ('rbxassetid://5516799190')
		game.Players.LocalPlayer.Character.Animate.idle.Animation1.AnimationId = ("rbxassetid://5516757431")
		_G.PlayAnim:Stop()
	end
end)

The problem is its the animation is not unloading (Stopping).

You cant change the Char from the Local player because the player is in the Workspace.
