If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
Can you please indicate if you are still having issues. I have just cloned your form and was not able to replicate the issue you indicate. When trying to submit information, I get the following warning if the fields are not filled properly.
We are constantly getting responses where that field is not completed but have a submission. I've doubled checked to ensure it's a required field, but they are frequently blank.
I did test your form and did not find any issue with that. The required validation is triggered correctly. Can you please embed your form using its iFrame embed code and see if that solves your problem? The following guide should should help you how to grab your form's iFrame embed code: http://www.jotform.com/help/148-Getting-the-Form-iFrame-Code
We will wait for your response.
