Script won't work??

Hi, I am making a terminal for a war group. But the script won't work? There is a model in Workspace called as Terminal and inside that there is a part called as Beam. Inside the beam there is a script called as RaidScript. And Inside the RaidScript there is a GUI named as CaptureGUI. Now the problem is that the GUI Text won't change and the beam color won't change. Here's the script:

script.CaptureGUI:Clone().Parent = game.StarterGui
timeuntilwin = 1200
totaltime = 1200
h = game.Players.LocalPlayer.PlayerGui.CaptureGUI.Hint
defendteamcolor = "Smoky grey"
raidteamcolor = "Bright red"
status = h.Parent.Status
winscreen = h.Parent.Win
winmsg = h.Parent.WinText

function OnTouched(hit)
    if hit.Parent:findFirstChild("Humanoid") ~= nil then
        if game.Players:GetPlayerFromCharacter(hit.Parent).TeamColor == BrickColor.new(raidteamcolor) then
            script.Parent.BrickColor = BrickColor.new(raidteamcolor)
            timeuntilwin = totaltime

        end
        if game.Players:GetPlayerFromCharacter(hit.Parent).TeamColor == BrickColor.new(defendteamcolor) then
            script.Parent.BrickColor = BrickColor.new(defendteamcolor)
            timeuntilwin = totaltime
        end
    end
end
script.Parent.Touched:connect(OnTouched)

while true do
    wait()
    if script.Parent.BrickColor == BrickColor.new(raidteamcolor) then
        h.Text = "Raiders will win in".." "..timeuntilwin
        if timeuntilwin <= totaltime and timeuntilwin > 0 then
            wait(1)
        timeuntilwin = timeuntilwin - 1 end
        if timeuntilwin == 0 then
            h.Text = " "
            status.Visible = false
            winscreen.Visible = true
            winmsg.Text = "Raiders have won!"
            wait(5)
            winscreen.Visible = false
            status.Visible = true
            h.Text = "Raid has got over."
        else
            if script.Parent.BrickColor == BrickColor.new(raidteamcolor) then
                h.Text = "Defenders will win in".." "..timeuntilwin
                if timeuntilwin <= totaltime and timeuntilwin > 0 then
                    wait(1)
                tiemuntilwin = timeuntilwin - 1 end
                if timeuntilwin == 0 then
                    h.Text = " "
            status.Visible = false
            winscreen.Visible = true
            winmsg.Text = "Defenders have won!"
            wait(5)
            winscreen.Visible = false
            status.Visible = true
            h.Text = "Raid has got over."

                end
            end
        end
    end
end

All the names are correct. Can someone please tell me what mistake I have done? Thank you for helping/reading. :)
