Dragging dead players not working?

So, I'm okay at scripting not the best. This is a re-post because my other anwsers just didn't work. Anyways here's the script I need help with.

local playerModel = script.Parent
local humanoid = playerModel:WaitForChild("Humanoid") 
local userInputService = game:GetService("UserInputService") 

local partA = playerModel.HumanoidRootPart 
local attachmentA = Instance.new("Attachment",partA)
local attachmentAPos = attachmentA.Position 
attachmentAPos = Vector3.new(0,0,-1)

local partB = script.Parent.RightHand 
local attachmentB = Instance.new("Attachment",partB) 
local attachmentBPos = attachmentB.Position
attachmentBPos = Vector3.new(0,0,-1)

humanoid(function(player) player.CharacterAdded:Connect(function(character) character:WaitForChild("Humanoid").Died:Connect(function() if humanoid.Health >= 0 then local distance = (partA.Position - partB.Position).magnitude

				if distance == 10 then


	userInputService.InputBegan:Connect(function(input, gameProcessedEvent)
	if input.UserInputType == Enum.UserInputType.Keyboard then if input.InputKeycode == Enum.KeyCode.E then local rodConstraint = Instance.new("RodConstraint",partA) rodConstraint .Attachment0 = attachmentA rodConstraint .Attachment1 = attachmentB


	               end
            end
           end)
        end
    end
end)
end) 
end)

It says Workspace.darkkitten12345.LocalScript:15: attempt to call a Instance value. I REALLY need help on this, thank you.

local attachmentA = Instance.new("Attachment",partA) 
local attachmentAPos = attachmentA.Position
attachmentA.Parent = "insert parent here"

You forgot to parent the attachment somewhere, thats why its causing an error
