[Solved] Help with a Receipt System

Update: Solved my self after a while.

So I’m making a Dashboard for a Handyman Company that is with a Custom Invoice (Receipt), Estimate system and on the Invoice I have a Items button that goes into another popup where you can search all Items/Services & Goods that the company will have for example Maintenance and Dry wall Repair is a couple items, I have the popup sending the data to the the invoice popup on a input, but when I go to add another item it replaces the original item and price, I would like it to add another line with the second item third item or how ever many items they need to add to that receipt, and for the prices to add and get put into the total input section and I use Inputs instead of text so the said company can change price if they want to add a discount
