how do i accuses a folder via a script that is named after a player?

the title explains it well but to reiterate I'm trying to access a folder that is named after a player but I have no clue how to do that here's what code that I have:

game.Players.PlayerAdded:Connect(function(player)
    Instance.new('Folder',workspace)
    workspace.Folder.Name = player.name

    local folder = workspace.. player.Name

    Instance.new('NumberValue',folder)
end)
