    Form ID can't start with numeric so it doesn't correctly validate. Please fix it JotForm.

    Can you give a little more detail about the problem and where you see it?

    But I think I've already said everything :) Do you know what HTML Validation is? I'm sure that yes. So it's incorrectly to name form ID using only numbers, or only just starting it with a number. So "123456" id incorrect, but "form_123456" is correct. Here's error from W3C


    Error Line 645, Column 116value of attribute "id" invalid: "1" cannot start a name 

    … method="post" name="form_12973039380" id="12973039380" accept-charset="utf-8">

    It is possible that you violated the naming convention for this attribute. For example, id and name attributes must begin with a letter, not a digit.


    Another error:

     Line 656, Column 58reference to non-existent ID "input_9" 

    …el class="form-label-left" id="label_9" for="input_9"> Imię i nazwisko </label>

    This error can be triggered by:

    A non-existent input, select or textarea element A missing id attribute A typographical error in the id attribute

    Try to check the spelling and case of the id you are referring to.


    and there is also one more error that there isn't input type="email" but I have changed it manually to input type = "text".

    OK Got it.

    I will ask the developers to consider this, but it may not be priortised as it doesnt affect form functionality or availability in any way, but I do understand why you would want it addressed. 

    Thanks for taking the time to make us aware of the issue.

    I also have many validation "errors" with the form from jotform - though it functionally works great. this is the only page on my website that won't pass the w3 validations due to various error. www.wayconmfg.com/contact.html

    see link: http://validator.w3.org/check?uri=http%3A%2F%2Fwww.wayconmfg.com%2Fcontact.html&charset=%28detect+automatically%29&doctype=Inline&ss=1&outline=1&group=0&st=1&user-agent=W3C_Validator%2F1.3

    Well now, I take it as being marked 'Priority:Important' means nothing as everything is the same. Site validation is very important to many and it would be greatly appreciated if you folks would step up and fix the issues with the coding.
