How do I make this work? It is an owner door for a tycoon and I can't tell what's wrong with it.

local Essentials = script.Parent:WaitForChild("Essentials")
local Door = Essentials:WaitForChild("Door")
local DoorOwner = Door.Mainpiece:WaitForChild("OwnerValueOfDoor")
local TycoonInfo = script.Parent:WaitForChild("TycoonInfo")
local OwnerValue = TycoonInfo:WaitForChild("Owner")

Door.MainPiece.Touched:connect(function(Hit)
    if Hit and Hit.Parent and Hit.Parent:FindFirstChild("Humanoid") then
        local Player = game.Players:GetPlayerFromCharacter(Hit.Parent)
        if Player and OwnerValue.Value == "" then
            OwnerValue.Value = Player
            if Player.Name == OwnerValue.Value then
                Door.MainPiece.CanCollide = false
                Door.MainPiece.BillboardGui.OwnerLabel.Text = "Owner: " .. tostring(OwnerValue.Value.Name)
            end
        end
    end
end)

I'm trying to make a claim door for a Roblox tycoon and currently, I'm stuck trying to figure out how to get it to update values. I want to be able to check if a player is the owner later on so that I can make it into an owner only door.

Edit: I forgot to say that currently I'm just trying to check if a door doesn't have an owner and if it doesn't I want the person touching it to become owner.

Edit 2: I just changed the code and did some testing. It isn't working on the part that checks if no owner. "if Player and OwnerValue.Value == "" then"

Final Edit/ Answer: This is the answer and the solved code:

game.Players.PlayerAdded:Connect(function(Player)
    local TycoonNumber = Instance.new("IntValue")
    TycoonNumber.Name = "TycoonNumber"
    TycoonNumber.Parent = Player
end

in a serverscript and then after creating a bool called TycoonTaken:

Door.MainPiece.Touched:Connect(function(Touch)
    if Tycoon.TycoonTaken.Value == false then
        if game.Players:GetPlayerFromCharacter(Touch.Parent) then
            local Player = game.Players:GetPlayerFromCharacter(Touch.Parent)
            Player.TycoonNumber.Value = 1
            OwnerValue.Value = Player
            Door.MainPiece.Transparency = 0.5
            Door.MainPiece.BillboardGui.OwnerLabel.Text = "Owner: " .. tostring(OwnerValue.Value.Name)
            Door.MainPiece.CanCollide = false--You could also change transparency here
        end
    elseif Tycoon.TycoonTaken.Value == true then
        if game.Players:GetPlayerFromCharacter(Touch.Parent) then
            local Player = game.Players:GetPlayerFromCharacter(Touch.Parent)
            if Player.TycoonNumber == Tycoon.TycoonNumber.Value then

            end
        --else
                --Touch.Parent.Humanoid.Health = 0
        end
    end
end)

Door being already declared and the mainpiece is the part with collision and color.
