Why is .Touched not working?(more details)

The title says it, i cannot find out what's wrong.

plr = game.Players[script.Parent.Parent.Name]
kamehameha = script.Parent
kamehameha.Touched:Connect(function(hit)
	print("touched")
	if hit.Parent:FindFirstChild("Humanoid") == true then
		humtodmg = hit.Parent:FindFirstChild("Humanoid")
		humtodmg.Health = humtodmg.Health - plr.Stats.KiMax/10
	end
end)

also this script is disabled and it gets undisabled when this script copies it into a part.

	blast = Instance.new("Part")
	blast.Name = "blast"
	blast.Shape = "Cylinder"
	blast.BrickColor = BrickColor.new("Toothpaste")
	blast.Transparency = 0.1
	blast.Material = "Neon"
	blast.CFrame = CFrame.new(ctr.HumanoidRootPart.CFrame.lookVector * 39 + ctr.HumanoidRootPart.CFrame.Position)
	blast.CFrame = CFrame.new(blast.CFrame.Position, ctr.HumanoidRootPart.CFrame.Position) * CFrame.fromEulerAnglesXYZ(0, math.rad(90), 0)
	blast.Anchored = true
	clone2 = clone:Clone()
	clone2.Parent = blast
	clone2.Disabled = false
	clone2 = nil
	blast.Size = Vector3.new(75,5,5)
	blast.CanCollide = false
	blast.Parent = ctr

clone2 is the clone of the script on the top

hit.Parent:FindFirstChild("Humanoid") == true is the possible error... Doing if hit.Parent:FindFirstChild("Humanoid") or if not hit.Parent:FindFirstChild("Humanoid") work for sure, unsure if it'd help.
