How would I make a timer that uses an IntValue? {Unsolved}

Well you don't exactly need a IntValue to make a timer script. game.Workspace.StarterGui.TimerSet.Frame.Time.Script StarterGui is not a child of workspace, it is the child of the game and will be defined like this game.StarterGui.TimerSet.Frame.Time.Script In this case i'll show you an example how I would do it

Let's say there is an order in StarterGui

ScreenGui

Frame

TextLabel

for i,v in pairs(game.Players:GetPlayers()) do
Time = 30 -- 30 seconds
for i = Time,0,-1 -- It minus 30 by 1(look at wait) , that zero in the middle is that it stop at 0.
Time = i
v:WaitForDataReady("StarterGui").ScreenGui.Frame.TextLabel.Text = ""..Time -- Get's all the players TextLabel And changes the time!!
wait(1) -- For every 1 second it subtracts 1 from Time which is equal to 30.
end
end

Ok, there you have your script inside the Gui and an IntValue in your Workspace, called Timer. The Gui has a text label and the time will be set in seconds.

timer = game.Workspace.Timer
text = script.Parent.TextLabel -- or wherever it is
timer.Changed:connect(function() -- runs everytime the value changes
    if timer.Value < 60 and timer.Value > 0 then -- if it's less than 1 minute
        text.Text = tostring(timer.Value) .. " second(s) left" -- turns the value into text
    elseif timer.Value >= 60 and timer.Value > 0 then -- if it's more than one minute
        seconds = timer.Value % 60 -- subtracts the minutes and leave the seconds
        minutes = math.floor(timer.Value / 60) -- takes the minutes
        text.Text = tostring(minutes) .. " minute(s) and " .. tostring(seconds) .. " second(s) left" -- bring both to text
    else -- when it's over
        text.Text = "Game Over!"
        -- run some function to end the game
    end
end)

Inside the value this simple script:

script.Parent.Value = 120 -- the total time players have, in seconds
while true do --  a loop
    wait(1) -- wait 1 second
    script.Parent.Value = script.Parent.Value - 1 -- takes one second from the value
end

To start counting the time, just enable the script and you're done.

[Edit]

script.Parent.Value = 30 -- the first 30 seconds
while true do --  a loop
    wait(1) -- wait 1 second
    script.Parent.Value = script.Parent.Value - 1
end
script.Parent.Value = 720 -- the final 12 minutes
while true do --  a loop
    wait(1) -- wait 1 second
    script.Parent.Value = script.Parent.Value - 1
end
