I am trying to make a tazer and I keep on getting this error?

"Workspace is not a valid member of workspace" Does anyone know how to fix this?

script.Parent.Equipped:Connect(function(mouse)
	mouse.Button1Down:Connect(function(plr)
		local bullet = Instance.new("Part",workspace)
		bullet.Transparency = 1
		bullet.Position = script.Parent.Handle.Position
		while true do wait(.01)
			bullet.Touched:Connect(function(plr)
				if plr.Parent:FindFirstChild("Humanoid") then
					if plr.Parent.Name == game.Workspace[script.Parent.Parent.Parent.Name].Name then
						wait(.1)
					else
						plr.Parent.Humanoid.PlatformStand = true
						wait(5)
						plr.Parent.Humanoid.PlatformStand = false
					end
				else
					if plr.Name == "Handle" and plr.Parent.Name == "Tazer" then
						--nothing
					else bullet:Destroy() end
				end	
			end)
		end
	end)
end)

edit: nvm I found the solution

script.Parent.Equipped:Connect(function(mouse)
	mouse.Button1Down:Connect(function(plr)
		local player = game.Players.LocalPlayer.Name
		local bullet = Instance.new("Part",workspace)
		bullet.Transparency = 0
		bullet.Position = workspace[player].Torso.Position
		while true do wait(.01)
			bullet.Position = Vector3.new(bullet.Position.X + 1,bullet.Position.Y,bullet.Position.Z)
			bullet.Touched:Connect(function(plr)
				if plr.Parent:FindFirstChild("Humanoid") then
					if plr.Parent.Name == game.Workspace[player].Name then
						wait(.1)
					else
						plr.Parent.Humanoid.PlatformStand = true
						wait(5)
						plr.Parent.Humanoid.PlatformStand = false
					end
				else
					if plr.Name == "Handle" and plr.Parent.Name == "Tazer" then
						--nothing
					else bullet:Destroy() end
				end	
			end)
		end
	end)
end)
