How do I fix my product variants so the price actually changes when a customer clicks “Large”?

Product variant price freezing is caused by missing dynamic product script bindings in your theme’s JS, or broken HTML variant selectors that fail to report variant changes back to the page container.

“Most minor website breaks are caused by simple script conflicts, legacy code blocks, or broken API handshakes. We identify and clear these issues immediately as a straightforward, one-time fix.”
