My output says Argument 1 missing or nil from a remoteevent , help?

so I am trying to make it so when a player clicks it adds a value to leaderstats, I am using a RemoteEvent on line 16 to connect with the server, The error also comes from the remote event.

local Tool = script.Parent;
local Player = game.Players.LocalPlayer

enabled = true




function onActivated()
    if not enabled  then
        return
    end

    enabled = false
    game.ReplicatedStorage.Click:FireClient()
        wait(.3)



    Tool.GripForward = Vector3.new(-0.976,0,-0.217)
    Tool.GripPos = Vector3.new(.95,-0.76,1.4)
    Tool.GripRight = Vector3.new(0.217,0, 0.976)
    Tool.GripUp = Vector3.new(0,1,0)


    Tool.Handle.DrinkSound:Play()

    wait(.8)

    local h = Tool.Parent:FindFirstChild("Humanoid")
    if (h ~= nil) then
        if (h.MaxHealth > h.Health + 1.6) then
            h.Health = h.Health + 1.6
        else    
            h.Health = h.MaxHealth
        end
    end

    Tool.GripForward = Vector3.new(-0.976,0,-0.217)
    Tool.GripPos = Vector3.new(0.3,0,0)
    Tool.GripRight = Vector3.new(0.217,0,-0.976)
    Tool.GripUp = Vector3.new(0,1,0)

wait(3)
    enabled = true


end

function onEquipped()
    Tool.Handle.OpenSound:play()
end

script.Parent.Activated:connect(onActivated)
script.Parent.Equipped:connect(onEquipped)
