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)
