How can I fix touch and activate problem of tool?

Greetings!

I have been working on a tool with attack, run, idle animation and I have little problem with Touched event. The problem is when I click, animations plays and then if I come next to goblin and if my "Blade" in tool touches the goblin's Humanoid, goblin will lose damage. I don't want that. I want when I click somewhere and come with my "Blade" next to goblin he won't take damage. Only when I activate the tool and my "Blade" touches him in same time he will take damage. I hope you understood. Here is the script I have problem with:

local CanAttack = true

script.Parent.Activated:Connect(function()
	if CanAttack == true then
		local tool = script.Parent.Parent
		local idle2 = script.Parent.Parent.Humanoid:LoadAnimation(script.Parent.LocalScript.Idle2)
		local attack = script.Parent.Parent.Humanoid:LoadAnimation(script.Parent.LocalScript.Attack)
		local run = script.Parent.Parent.Humanoid:LoadAnimation(script.Parent.LocalScript.Run) 
		local idled = script.Parent.Parent.Humanoid:LoadAnimation(script.Parent.LocalScript.IdleDefault)
	    local Humanoid = script.Parent.Parent.Humanoid
	    idle2:Stop()
	    CanAttack = false
	    attack:Play()
		script.Parent.Blade.Touched:Connect(function(hit)
				if hit.Parent.Humanoid and script.Parent.CanDamage.Value == true then
				hit.Parent.Humanoid:TakeDamage(30)
				script.Parent.CanDamage.Value = false
			end
	    end)
	    if Humanoid.MoveDirection.Magnitude > 0 then
	        run:Play()
		    else
				idle2:Stop()
				run:Stop() print("Stop running -- line 64")
		end
	    CanAttack = true
	    script.Parent.CanDamage.Value = true
	end
end)
