Мне нужна помощь в добавлении еще одного поля количества в этот код ⇐ Php

[Anonymous]

У меня есть POS-система, которая пытается вручную добавить продажу, и мне нужно добавить поле количества, аналогичное тому, которое уже есть, чтобы оно было помечено как бонус, поэтому, когда вы добавляете введенные значения для обоих начальных количеств, и поле бонусного количества, они будут соответствовать общему количеству поставленных товаров.
Вот код (его частичная часть):
`

var count = 1, an = 1, product_variant = 0, DT = ,
product_tax = 0, invoice_tax = 0, product_discount = 0, order_discount = 0, total_discount = 0, total = 0, allow_discount = ,
tax_rates = ;
//var audio_success = new Audio('sounds/sound2.mp3');
//var audio_error = new Audio('sounds/sound3.mp3');
