game:GetService('UserInputService').InputBegan:connect(function(input)
	if input.KeyCode == Enum.KeyCode.LeftControl then
		Rlooping = true
		
		toolNone.AnimationId = 'http://www.roblox.com/asset/?id=476682284'
		walk.AnimationId = 'http://www.roblox.com/asset/?id=476653440'
		print(walk.AnimationId)
		humanoid.WalkSpeed = 80
	elseif
		 input.KeyCode == Enum.KeyCode.LeftControl and toolNone.AnimationId == 'http://www.roblox.com/asset/?id=476682284' and walk.AnimationId == 'http://www.roblox.com/asset/?id=476653440' then
		toolNone.AnimationId = 'http://www.roblox.com/asset/?id=448766294'
	
		walk.AnimationId = 'http://www.roblox.com/asset/?id=476341652'
		humanoid.WalkSpeed = 16
	end
end)

the code works for a few seconds after i click the button, and it doesnt revert to the old animation when it is clicked again
