I received the submissions as 'undefined' in the email but they are there when you login to Jotform

It's the email template with 'undefined' text. Please do the following to fix the problem:

1. Delete the current email template, guide to delete here: https://www.jotform.com/help/132-How-to-Delete-Notifications-Autoresponder.

2. Create a new email template, guide here: https://www.jotform.com/help/25-Setting-Up-Email-Notifications.

Lastly, I noticed that you have embedded the form on your Wix website as an iframe. To avoid possible issues in the future, we suggest following our embed method in the guide below for Wix:
