I’m dealing with a stubborn form-validation error on the checkout page. Shoppers complete the form, hit “Submit,” and the page still marks required fields as invalid, blocking the sale. I’m not sure whether the credit-card, billing-address, or email inputs are at fault, so the first step is pinning down the real culprit. Here’s what I need from you: • Inspect the checkout code—client and server side—to locate the source of the validation failure. • Fix the logic or scripting so correctly entered data passes cleanly while genuine errors show accurate messages. • Test the corrected checkout flow in mainstream browsers and on mobile. • Send me a brief report outlining the issue, the changes made, and any preventive suggestions. I’ll supply repository or staging access as soon as we start. If you have solid experience debugging e-commerce forms and can turn this around quickly, I’m ready to get this resolved today.
