Script doesn't see a model in my Player. Can someone help me?

Hello. I am making a script that plays an animation (sword is auto equipped without a tool.) Apparently, the script says there is no model called "Blade" in workspace.luvumilo (luvumilo is my username.) Here is the code

local chr = script.Parent.Parent.Parent.Parent.Character
Animationplay = true
scissorblade = chr["Blade"]
dmg = scissorblade.dmg.Script
dmg.Disabled = true
button = script.Parent
button.MouseButton1Down:Connect(function()
	if Animationplay == true then
		local attack = chr.Humanoid:LoadAnimation(script.Attack)
		dmg.Disabled = false
		attack:Play()
		Animationplay = false
		chr.Humanoid.WalkSpeed = 0
		wait(.5)
		dmg.Disabled = true
		chr.Humanoid.WalkSpeed = 60
		Animationplay = true
	end
end)

Output says that on line 3, "Blade is not a valid member of Model "Workspace.luvumilo". I've tried changing the code over and over again, but nothing has worked. If anybody knows how to fix this problem, please answer or comment. Extra info: Script is in a TextButton inside of a ScreenGui inside of StarterGui (which goes inside the LocalPlayer when server is launched)
