@arbu1499

I’ve carefully reviewed the issue—your current Shopify theme’s variant JS is failing with multi-option products, causing incorrect availability, broken Add to Cart / Make a Request logic, and unreliable notify-me integrations. I would rebuild the variant detection layer to use Shopify’s native product JSON as the single source of truth, bind clean change listeners to all option selectors, resolve the active variant deterministically on every change, and trigger centralized UI updates (price, availability, button state, third-party events) including the dynamic €1,000 price-based button switch. Fixed Price: €350 Timeline: 5–7 days (including testing across variant combinations and app integrations) Looking forward for your positive response in the chatbox. Best Regards, Arbaz T

I understand that you're experiencing critical issues with your Shopify product variant logic, and I sympathize with the frustration and impacts this has on your business. With over 10 years of experience as a web engineer, I've tackled and solved numerous complex issues similar to yours, making me the perfect fit for your project. My profound knowledge of Shopify themes and JavaScript ensures that I am fully equipped to analyze and rebuild your variant logic to recognize the selected variant without fail, no matter how many option combinations are involved. Moreover, I'll ensure that all relevant UI elements update immediately and correctly after changes are made, leaving no room for glitches. Notably, I appreciate the need for a maintainable and future-proof solution rather than temporary fixes or workarounds. My technical skills are complemented by my commitment to clean and reliable development practices, emphasizing long-term stability. You can count on me for transparent communication regarding the budget, timeline, and technical approach we'll take to provide you with an exemplary Shopify store experience. Let's get started!

@FizzaNadeemK

Hi, I’ve worked on complex Shopify themes where multi-variant logic breaks exactly the way you described—especially when availability, price display, and third-party notify apps depend on accurate variant detection. If the current script only evaluates on page load, that explains the inconsistent button and UI behavior. My approach would be to fully refactor the variant handling using Shopify’s native product JSON and a single source-of-truth function that recalculates the selected variant on every option change. I’ll bind listeners properly, ensure availability and price update instantly, and make the “Make a Request” switch react dynamically when the price exceeds 1,000 €. I’ll also audit integration events so your notify-me app always receives the correct variant ID. The result will be clean, maintainable code without patchwork fixes. Estimated timeline: 2–3 days Fixed price: €250 If you’d like, I can briefly review your theme structure and confirm scope before we finalize. Best Regards, Fizza Nadeem K

@Syedh1998

I can fix your Shopify multi-variant issues by rewriting the JavaScript to reliably detect every selected combination, update UI elements in real-time, and ensure all third-party integrations like notify-me work flawlessly. The current issues—broken “Add to Cart” behavior, static price-based “Make a Request” buttons, and inconsistent availability—will be fully resolved. I’ll implement dynamic price checks so buttons switch instantly when variant price crosses 1,000 €, and inventory, price, and availability all refresh immediately on option change. The code will be modular, maintainable, and future-proof, with clear comments and short documentation. Estimated timeline: 1–2 business days, including testing across multiple products. Fixed price: $250 USD (adjustable depending on product volume). Deliverables include fully working variant logic, dynamic UI updates, and verified integration with all existing apps. This approach ensures seamless customer experience, accurate variant handling, and clean, easily maintainable code for future Shopify updates. Syed

@shabahathabib

Hi, I understand the issue: your current JS only handles single-variant logic, causing incorrect variant detection, broken availability states, price mismatches, and unreliable third-party app triggers once multiple options are involved. I’ll rebuild the variant selection logic to reliably resolve the active variant on every option change and immediately sync price, availability, button state, and integration events. Technical approach: Refactor around Shopify’s variant object + option mapping (no hacks). Centralized variant-change handler. Dynamic €1,000 price check to toggle “Add to Cart” / “Make a Request.” Ensure compatibility with notify-me app events. Clean, maintainable, future-proof code with testing and revisions included. Ready to start immediately. BEST REGARDS SHABAHAT HABIB*
