Why does my sword only do damage once after hitting an enemy?

I am working on a sword right now and everything is fine and perfect until I found out that my sword can only deal damage once and once only. I made another question on how to make the sword only deal damage when it was clicked and it's fixed, but now it created another problem, which is this. All the animation works, the main problem is just that it's only doing damage once. Please help!

Local Script

local CanAttack = true
local player = game.Players.LocalPlayer
local char = player.Character or player.CharacterAdded:Wait()
local idle = char:WaitForChild("Humanoid"):LoadAnimation(script.idle)
local attack = char:WaitForChild("Humanoid"):LoadAnimation(script.attack)
script.Parent.Equipped:Connect(function()
    idle:Play()
    script.Parent.Activated:Connect(function()
        if CanAttack then
            idle:Stop()
            attack:Play()
            CanAttack = false
			idle:Play()
            wait(1)
            attack:Stop()
            CanAttack = true
            script.Parent.CanDamage.Value = true
        end
    end)
end)
script.Parent.Unequipped:Connect(function()
	idle:Stop()
end)

** Normal Script**

script.Parent.blade.Touched:Connect(function(p)
	if script.Parent.CanDamage.Value ==  true then
		p.Parent.Humanoid:TakeDamage(20)
		script.Parent.CanDamage.Value = false
	end
end)

make the script like this (i think):

script.Parent.blade.Touched:Connect(function(p)
	if script.Parent.CanDamage.Value ==  true then
		script.Parent.CanDamage.Value = false
       		p.Parent.Humanoid:TakeDamage(20 + math.random(1,20))
		script.Parent.CanDamage.Value = true
    	end
end)

There was a CanDamage value blocked to make debounce so you can add some random number instead.
