I have an error assigning a value, how can I fix it?

So I'm trying to assign an airport to the player when the enter the game but it isn't working correctly and there is no output, yes there is a connection line, I just didn't feel like posting the rest of the script:

function PlayerEntered(player)
    print(player.Name .. " entered the server") 
    --Stats
    airport = Instance.new("IntValue", player)
    airport.Name = "Airport"
    airport.Value = "None"
    --
    wait()
    --Assigning Airport
-------------------------------This part doesn't execute for some reason?
    for _,v in pairs(game.Workspace.Airports:getChildren()) do
        if airport.Value == "None" then
            if v.Owner.Value == "None" then
                airport.Value = tonumber(string.sub(v.Name,7,8))
                v.Owner.Value = player.Name
            end
        end
    end
-------------------------------
end
