I tried making my punch script server sided but it doesn't work?

I used a YouTube tutorial to help me make a punch script. Everything worked perfectly except for the fact that the damage was client-sided. So just now I tried making it server-sided; it was kinda thrown together with the help of some research and extra tutorials, and it was a bit hard for me to imagine so I could put it together, so it may just be my own brain's fault. Here are the scripts:

Local Script Activates the animation, sends out the remote event, etc

CanDoDmg = true
Keybind = "q"
dmg = 10

local plr = game.Players.LocalPlayer
local mouse = plr:GetMouse()

local ReplicatedStorage = game.ReplicatedStorage
local PunchHit = ReplicatedStorage.RemoteEvents.PunchHit

local Damage = game.Workspace.Damage
local PlayerHit = game.Workspace.PlayerHit

mouse.KeyDown:Connect(function(key)
	if key == Keybind then
		local anim = script.Parent.Humanoid:LoadAnimation(script.Animation)
		anim:Play()
		script.Parent.RightHand.Touched:connect(function(hit)
			if hit.Parent.Humanoid and CanDoDmg == true then
			PlayerHit = hit.Parent
			Damage = dmg
			PunchHit:FireServer()
			-- hit.Parent.Humanoid:TakeDamage(dmg)
			CanDoDmg = false
			wait(1)
			CanDoDmg = true
			end
		end)
	end
end)

Server Script Receives the remote event and executes the damage

local ReplicatedStorage = game.ReplicatedStorage
local PunchHit = ReplicatedStorage.RemoteEvents.PunchHit

local Players = game.Players

local Damage = game.Workspace.Damage
local PlayerHit = game.Workspace.PlayerHit

local Plr = ""

PunchHit.OnServerEvent:Connect(function()
	Plr = PlayerHit
	Players.Plr.Humanoid:TakeDamage(Damage)
end)
