Make a number into a shortcut(?)

I'm trying to make a script that changes a gui text to show "1m" instead of "1000000" as it's more neater and easier to read. I found a script that I could use but I'm not exactly 100% sure on how to use it on a gui text, here's the script in my gui:

script.Parent.Text = game.Players.LocalPlayer.leaderstats.Cash.Value
while true do
	wait(0.1)
	script.Parent.Text = game.Players.LocalPlayer.leaderstats.Cash.Value
end

Here is the script I found but I tried using but couldn't get it to work:

local suffixes = {"K", "M", "B", "T", "Q", "Qu", "S", "Se", "O", "N", "D"}

local function toSuffixString(n)
    for i = #suffixes, 1, -1 do
        local v = math.pow(10, i * 3)
        if n >= v then
            return ("%.0f"):format(n / v) .. suffixes[i]
        end
    end
    return tostring(n)
end

script.Parent.Text = toSuffixString(game.Players.LocalPlayer.leaderstats.Cash.Value)

If you know how fix this, please let me know.

it is easy! Do it like:

local StarterGui = __________ -- Show startergui here
--Show like script.parent.parent.parent...(etc until it comes to the StarterGui)
--As you should use a normal script, using game.Players.LocalPlayer won't work

local cash = StarterGui.Parent.leaderstats.cash

cash.Changed:Connect(function()
	if cash.Value >= 1000 and cash.Value < 1000000 then
		local shortened = tostring(cash.Value/1000)
		script.Parent.Text = (string.sub(cash, 1, 2).."K")
	elseif cash.Value >= 1000000 and cash.Value < 1000000000 then
		local shortened = tostring(cash.Value/1000000)
		script.Parent.Text = (string.sub(cash, 1, 2).."B")
	elseif cash.Value >= 1000000000 and cash.Value < 1000000000000 then
		local shortened = tostring(cash.Value/1000000000)
		script.Parent.Text = (string.sub(cash, 1, 2).."T")
		--keep continuing like that
	end
end

And also, make sure you use a Normal script to increase the currency and put this script too as a normal script. Both should be normal script to work.

Just made a script that would do what you wanted, rather than changing your cash varable to a string vale i would leave that as a Number value and just hook up the function you found to the readout on your gui, Something like:

Gui Code: (Local Script)

local function toSuffixString(n)
	local suffixes = {"K", "M", "B", "T", "Q", "Qu", "S", "Se", "O", "N", "D"}

	for i = #suffixes, 1, -1 do
		local v = math.pow(10, i * 3)
		if n >= v then
			return ("%.0f"):format(n / v) .. suffixes[i]
		end
	end
	return tostring(n)
end

--// this just changes your cash value so it shows the base 10 names in your suffixes table by powering it by 10 aka `10^0 = 1` , `10^1 = 10`, `10^2 = 100` etc....

spawn(function()
for i=0,35 do
	game.Players.LocalPlayer.leaderstats.Cash.Value = 10^i	
	wait(.1)
end
end)

script.Parent.Frame.Cash.Text = toSuffixString(game.Players.LocalPlayer.leaderstats.Cash.Value)
while true do
	wait(0.1)
	script.Parent.Frame.Cash.Text = toSuffixString(game.Players.LocalPlayer.leaderstats.Cash.Value)
end

And just incase the server script im using:

Code:

local Players = game:GetService("Players") 
Players.PlayerAdded:connect(function(plr)

	local LS = Instance.new("NumberValue",plr)
	LS.Name = "leaderstats"


	local Cash = Instance.new("NumberValue",LS)
	Cash.Name = "Cash"
	Cash.Value = "0"
end)

Hope this helps! :)
