How to assign an int value based on a model int value when a player joins the server?

Sorry if the title made no sense, english is not my native language.

What I'm doing is, I have a Model on Workspace called Factories, and inside, there's 8 models that are called Factory. I want to loop through each one, get the IntValue and StringValue from them, and depending on the StringValue value, assign the Factory IntValue to the player who just joined.

Workspace > Factories > Factory > FactoryNumber and OwnerName

this is my script so far, and it's not working, no errors are thrown on the console:

EDIT: it is inside the function that is connected to the PlayerAdded event.

for _,factory in pairs(game.Workspace.Factories:GetChildren()) do
        local isOwnedBy = factory.OwnerName
        local factoryNumber = factory.FactoryNumber
        local spawnPos = factory.SpawnPoint.Position

        local playerModel = Workspace:FindFirstChild(player.Name)

        if isOwnedBy.Value == "" and player.FactoryNumber.Value == 0 then
            player.FactoryNumber.Value = factoryNumber.Value
            isOwnedBy.Value = player.Name
            if playerModel:IsA("Model") then
                playerModel.Character.Torso.CFrame = spawnPos
            end
        end
    end

Is there something wrong with my script?
