script works perfectly fine in studio mode but doesn't in the actual game. Please help?!

I have a script that is supposed to punch whenever the f key is pressed, it works perfectly fine when I test it in studio mode, however, when I test it in the actual game it still does the animation but doesn't do any damage, and i'm not getting any errors in the output, so I don't know what is wrong with it. Please help.

This is the script that detects if the button is pressed and does the animation, it is a local script:

plr = game.Players.LocalPlayer
if plr.Character == nil then 
	repeat wait() until plr.Character ~= nil
end
char = plr.Character
debounce = false

function onKeyPress(input)
	if debounce == true then return end
	if input.KeyCode == Enum.KeyCode.F then 
		debounce = true
		a = Instance.new("Animation") 
		human = char:FindFirstChildOfClass("Humanoid")
		hitscript = script.Hit:Clone()
		hand = char:FindFirstChild("RightHand")
		arm = char:FindFirstChild("Right Arm")
			a.AnimationId = "rbxassetid://1056939487"
			a2 = human:LoadAnimation(a)
			a2:Play() 
			hitscript.Parent = hand
		end
		hitscript.Disabled = false
		wait(1)
		hitscript:Destroy() 
		debounce = false
end

game:GetService("UserInputService").InputBegan:connect(onKeyPress)

This is the script that does the damage, it is a server script that is the child of the local script:

debounce = false

script.Parent.Touched:Connect(function(hit)
	if debounce == true then return end
	h = hit.Parent:FindFirstChildOfClass("Humanoid")
	if h then
		if hit.Parent.Name == script.Parent.Parent.Name then return end
		debounce = true
		h:TakeDamage(5)
		s = Instance.new("Sound", script.Parent)
		s.SoundId = "rbxassetid://329077052" 
		s.PlayOnRemove = true
		s:Destroy()
		wait(1)
		debounce = false
	end
end)
