Why is form being submitted without a required element?

Our form requires a phone number in order to be submitted however today we have received multiple forms without the phone number. This is a required element so we are needing to figure out why the form is being allowed to submit without this element. Thank you.

I opened your form and I can see that the required fields are working properly. I tried leaving the phone number blank and I wasn't able to submit the form. Here's a screen capture:

If this form is embedded on a webpage, please try re-embedding it using the iFrame method. This will prevent script conflicts between the webpage and the form. Here's a guide: Getting-the-form-iFrame-code.

Also, I've checked your submissions and I can see that the phone number is showing in the latest submissions. I also noticed that the phone number field is unchecked in the Submissions page. If this is unchecked, then the phone number will not show in the submissions.

Hope that helps. Let us know if you need further assistance. Thank you.
