Unable to submit the form - Error message

2 problems with form:  https://www.jotform.com/83395024863159

1) it said errors, but I don't see there is any error. There are only  very few  required fields and i did fill them all.  I don't see any error. 

2)  The "submit" button disappear after : 

a) after I saw the error, I went back to try refilling out some fields. 

b) scroll down, the submit button no longer there. 

Not sure if this is what the error as the field appears wth red border: 

but I don't see a problem with the field though. 

The issues are related to the Name fields that is an Email field. 

Please change the Email fields to the Full Name fields. 

I also noticed that a lot of the fields are Email fields. Please fix the issue and test your form again.

Thank you for your help.. I did not realize it... I should have done it by divide and conquer!!! 

We have moved your next question as new thread in order to address it as separate query: https://www.jotform.com/answers/1674562 

Thank you  again.  Would you tell me how to look up the ids so that I could be more self-efficient? 

I tried, but all I could find was #multiSelect-checkbox-133  .  

I can suggest to use 'Inspect Element' (right click on page) tool of a browser to find class or id selector:

Some IDs of fields are available via field properties: How-to-Find-Field-IDs-and-Names

We will gladly help if you face difficulties.
