I have about twenty curtain products built on WooCommerce, each already using the official “WooCommerce Product Add-Ons” plugin for extra options. Most of the size-based variables from my Excel sheet are in place (roughly 90 %), but they need a quick QA pass and any missing or incorrect values corrected—skip the green-highlighted rows, those are intentionally excluded. What still needs to be done: • Add a new add-on for “Installation side”: Right (₪0) or Left (₪80). • Add an add-on for “Curtain width shortening” with a fixed charge of ₪150 and an input box where shoppers can enter the final width. • Fix the live price calculator so selecting “Left” instantly adds ₪80, and the shortening option adds ₪150—changes must reflect in real time on the product page, not later in the cart or checkout. Once everything is wired up and tested, every product page should: – Show the complete, verified size list exactly as in my sheet. – Update the total price instantly when a shopper chooses an installation side or shortening. – Pass the selected options, prices, and custom width to the cart/order. All work must stay within the existing WooCommerce Product Add-Ons framework; no new premium plugins are required. I can supply the Excel file, product IDs, and staging credentials as soon as we start.
