JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
May we ask for the URL of the form you are referring to? I checked the forms in your account and none of them seem to be integrated with ZOHO crm.
If you are referring to this form (http://www.jotformz.com/form/53416002603643), the fields might not be recognized because the form is in a different language. Please remove the previous integration and try making your form multilingual by following this guide: How to make your forms multilingual? Then you can try reintegrating the form with zoho crm again.
Do let us know if the issue persist.
