Problem making my Gui show up at certain times?

So im making a game like work at a pizza place, the mainline of it is that you choose your job and then you work. the more things you get done the more money you get. When the serverTime is at a certain amount your paycheck shows up.

My problem:

I cant figure out the script for my ServerTime to go up... I made an intvalue in repstorage so yea.

I tried putting a script in server script storage but this does not work, the script was

local ServerTime = game.ReplicatedStorage.IntValue

While 100 == 100 do
	wait(1)
	ServerTime.Value = ServerTime.Value + 1

this should make it give me 1 servertime each second, Right?

my next script was my gui script, i put it inside the button (claimButton) this was it

local frame = game.StarterGui.MyScreenGui.Frame
local ServerTime = game.ReplicatedStorage.IntValue
local AmountForClaim = game.ReplicatedStorage.AmountPerClaim
local player = game.Players.LocalPlayer
local mouse = player:GetMouse
local Cash = player.leaderstats.Cash

while 100 == 100 do
	if ServerTime.Value == 10 then
		if frame.Visible == false then
			frame.Visible = true
			ServerTime.Value = 0

script.Parent.MouseButton1Click:Connect(function()
	player.Cash.Value = player.Cash.Value + AmountForClaim
	if frame.Visible == true then
	wait()
	frame.Visible = false

But it does not work ;( what can I do to fix this?

While I do know how to make your script work, this code is highly inefficient, so let's replace it with something else. Go ahead and add a RemoteEvent inside ReplicatedStorage, and let's call it, say GivePaychecks.

In ServerScriptService, go ahead and add a script and add the following lines of code:

--Script to fire the RemoteEvent every 100 seconds
--First, get ReplicatedStorage
local ReplicatedStorage = game:GetService("ReplicatedStorage")

--Get the remote event
local givePaychecks = ReplicatedStorage:WaitForChild("GivePaychecks")

--Seconds until the paychecks are given
local waitTime = 100

while true do
	--Wait until the time specified
	wait(waitTime)

	--Now fire the remote event to all clients
	givePaychecks:FireAllClients()
end

Make sure that you don't just copy and paste this script in, make sure you understand what every line is doing. I left comments in to help you. Now, replace the code in your GUI script with this:

--Get ReplicatedStorage
local ReplicatedStorage = game:GetService("ReplicatedStorage")

--Get remote event
local givePaychecks = ReplicatedStorage:WaitForChild("GivePaychecks")

--Get the frame
local paycheckFrame = game.StarterGui.MyScreenGui.Frame

--When the remote event is fired, execute the following code
givePaychecks.OnClientEvent:Connect(function()
	--If they are not collecting their other paycheck, then:
	if not paycheckFrame.Visible then
		print("Not receiving paycheck, giving paycheck now...")
		paycheckFrame.Visible = true
	else
		print("Currently receiving other paycheck")
	end
end)

Hope this helped!
