How do i check if a letter or a word is a part of a full string?

So, i have this script where i want the text to have a typewriting effect, but it keeps on doing it on the intermission and the map voting, so it will typewrite like this:

intermission: 15 intermission: 14

and so on untill it reaches 0.

how do i check if a word or letter is a part of the value?

here is my script:

local status = game.ReplicatedStorage:WaitForChild("Values"):WaitForChild("Status")
local sound = game.SoundService:WaitForChild("Talk")
local label = script.Parent

label.Text = status.Value

local function makeText(obj,text)
	for i = 1,#text,1 do
		obj.Text = string.sub(text,1,i)
		sound:Play()
		wait(0)
	end
end

status:GetPropertyChangedSignal("Value"):Connect(function()
	makeText(label,status.Value)
end)

help would be appreciated!
