Script that was working ~1 week ago no longer is?

This is a problematic script. I asked this question ~1 month ago, added WaitForChild to the second line, and that was that, everything was working fine again. However, the script broke again. It just doesn't work this time.

When the script is working, it brings up a GUI if someone's "Job" value is Job's default value. If the Job value is the name of the facility followed by the city it is in, it'll pay you for the delivery, add the miles you drove to the leaderstat, and reset everything. If your "Job" value is its default, it will create a random number between 1 and 3 and depending on that number it will update the GUI's text buttons and such with the properties of the job corresponding to that number.

There are no output errors or anything, it just doesn't work anymore. Does anyone know why?

    if hit.Parent:FindFirstChild("Humanoid") then
        if game.Players.LocalPlayer.Job.Value == "a" then
            Gui.Visible = true
            local number = math.random(3)
            if number == 1 then
            Gui.TextButton.Text = "SellGoods    -    Belfast ME"
            Gui.TextLabelMoney.Text = "553"
            Gui.TextLabel.Text = "46"
