Counting script not doing anything. What's wrong?

So I have these scripts : LocalScript in StarterPack (My guess would be the errors here somewhere, but yet again the value in the severstorage never changes)

song1 = game.Soundscape.puzzle
player = game.Players.LocalPlayer
player.PlayerGui:WaitForChild("ScreenGui")
gui = player.PlayerGui.ScreenGui.TextLabel
seconds = game.ServerStorage.seconds.Value

seconds = 30
if game.ServerStorage.roundover.Value == true then
gui.Text = "Next game starts in ".. seconds .." seconds!"
repeat 
gui.Text = "Next game starts in ".. seconds .." seconds!"
wait(1)
until
seconds == 0
end

Script in ServerScriptService

seconds = game.ServerStorage.seconds.Value
puzzle = game.Soundscape.puzzle
game.ServerStorage.roundover.Value = true

seconds = 30
if game.ServerStorage.roundover.Value == true then
	puzzle:Play()	
	repeat 
	seconds = seconds - 1
	wait(1)
until
	seconds == 0
	puzzle:Stop()
end

game.ServerStorage.roundover.Value = false

wait(5)

game.ServerStorage.roundover.Value = true

I want these scripts to (if you can't read it) make a gui count down, nothing happens, no error in the output, the text doesn't change. What's wrong?

I have a very simple script for you that works just fine! It even loops the song :) (or sound, your choice)

while true do
	wait(1)
	script.Parent.Sound:Play()
	wait(SOUNDLENGTH)
	wait(1)
end

If you do NOT want it to loop, do this:

roundStart = false

if roundStart == true then
	script.Parent.Sound:Play()
	wait(SOUNDLENGTH)
	roundStart = false
else
	wait()
end
