How is it possible that required fields are received empty?

I am receiving forms with fields that I have stipulated 'required' - empty.

Am I missing something?

Thanks

Try to re-embed your form with an Iframe code there might be a conflict with your webpage script and the embed code. Also, I notice that you are using a field with incorrect validation for example your "Your Email" field's validation is set to "None". If you set this to "None" user will be able to submit none email format so I suggest that you change this to "Email" or you can just use the email field under "Quick Tools" section.
