Does anyone know how to stop my Output from saying -Not a Valid Member?

So my Output is saying that "Humanoid is not a valid member of Workspace" and Humanoid is a valid member of my dummies and my dummies are in the Workspace. So whats up with that. Is Humanoid only a member in my dummies or what? I don't know? Anyways here is my script.

Normal Script for Damage:

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

Local Script for Animations:

local CanAttack = true

script.Parent.Equipped:Connect(function()
	local Idle = script.Parent.Parent.Humanoid:LoadAnimation(script.Idle)
	local Slash = script.Parent.Parent.Humanoid:LoadAnimation(script.Slash)
	
	Idle:Play()
end)

script.Parent.Activated:Connect(function()
	local Idle = script.Parent.Parent.Humanoid:LoadAnimation(script.Idle)
	local Slash = script.Parent.Parent.Humanoid:LoadAnimation(script.Slash)
	
	if CanAttack == true then
		Slash:Play()
		Idle:Stop()
		CanAttack = false
		wait(1)
		Slash:Stop()
		Idle:Play()
		CanAttack = true
		script.Parent.Value = true
end
end)
