I checked the webpage and I've found out that it is not a JotForm form. The import or clone form would only work with a JotForm forms. It can copy a direct link form or form that is embedded on a webpage.
If you look at the error - "Form not found: Form Id is missing or irregular". It means that there is no JotForm form ID found on the URL or in the webpage.
Just to let you know that we've updated our import tool and importing a form from a webpage is now possible. Please try it again and let us know if there are problems.
