How do i reference the player without a function?

so basically i need to reference X,Y,Z coordinates but i also need the player the problem is the player gets mixed with the Z coordinates and when i print it it says "jedistuff2,(my Y coordinates), (My X coordinates)

    game.ReplicatedStorage.CoordinatesX.OnServerEvent:Connect(function(X)
        game.ReplicatedStorage.CoordinatesY.OnServerEvent:Connect(function(Y)
        game.ReplicatedStorage.CoordinatesZ.OnServerEvent:Connect(function(Z)
            game.ReplicatedStorage.FloorPlace.OnServerEvent:Connect(function(Player)

    local Floor = Instance.new("Part", workspace)
    local FloorSize = Vector3.new(X, Y, Z)
    Floor.Name = "Floor"
    Floor.Size = FloorSize
    Floor.CFrame = CFrame.new(Player.Character["Left Leg"].Position) + Vector3.new(0,-1,0) 
    Floor.Anchored = true
    Floor.BrickColor = BrickColor.new("Pastel brown")
        Floor.Material = Enum.Material.WoodPlanks
        print(X,Y,Z)



    end)
    end)
    end)
    end)

heres the local script too

local Button = script.Parent
local player = game.Players.LocalPlayer
local mouse = player:GetMouse()
Button.MouseButton1Click:Connect(function()
    game.ReplicatedStorage.FloorPlace:FireServer()
    game.ReplicatedStorage.CoordinatesX:FireServer(script.Parent.X.Text)
    game.ReplicatedStorage.CoordinatesY:FireServer(script.Parent.Y.Text)
    game.ReplicatedStorage.CoordinatesZ:FireServer(script.Parent.Z.Text)

end)
