Solved Format currency

[Vini]

I've found a few posts about currency formatting, but I couldn't add them to my code
This is my code

command /withdraw <number> [<number>]:
    trigger:
        if arg-2 is not set:
            if player's balance >= arg-1:
                remove arg-1 from balance of player
                give player bamboo named "&aMoney Roll &8[&a$%arg-1%&8]" with lore "&fRight-Click to redeem" and "&7Rarity &a&lMONEY"

Now here: "give player bamboo named "&aMoney Roll &8[&a$%arg-1%]" with lore "&fRight-Click to redeem" and "&7Rarity &a&lMONEY" I'd like to format the arg-1 part to be like 1000: 1,000 | 10000: 10,000 | 100000: 100,000 etc.

I have no idea how I could start.
Can someone help?

function regex(n: object) :: text:
    if "%{_n}%" contains ".":
        set {_s::*} to split "%{_n}%" at "."
        set {_n} to "%a({_s::1})%.%last 2 characters of {_s::2}%"
        return "%{_n}%"
    else:
        set {_n} to a("%{_n}%")
        return "%{_n} ? 0%"

function a(b: text) :: text:
    if length of {_b} > 3:
        return "%a(first length of {_b} - 3 characters of {_b})%,%last 3 characters of {_b}%"
    return {_b}

The usage will be "&aMoney Roll &8[&a$%regex(arg-1)%&8]"

Thank you so much! It worked!
