    How Can I Force the Users to Fill Some of the Specific Fields?

    Asked by BespokeWealth on January 06, 2016 at 11:45 PM

    How can conditions be imposed before a form is submitted?

    For example, All required fields must be completed so that a form can be submitted else the uncompleted fields will be highlighted.

    Appreciate all advice. Thanks.

    Actually, making the fields "Required" is exactly making the same effect on your form. Please, see the sample run from the below:



    In addition, you can customize the default warning message "This field is required" on "Properties" of your form:


    So, you don't need to use conditions to actualize this scenario. For further assistance, please let us know.

    Hi mert,

    I have received submitted forms on more than one occasion in which some of the required fields are blank. I am unable to reproduce the errors as they have occurred on different forms.

    If your reply is correct, is there then a possibility in which data entered into the fields are lost during transmission to the the Jotform servers?

    If the form is embedded to a webpage and there are conflicts with other elements in the page, it can cause validation to fail.  There can also be some older browsers that may cause validation to fail.

    If your form is embedded to a webpage, replace your current embed code with the iframe code:


    This will greatly reduce and validation issues for embedded forms.

    I understand that it is impossible to use the iFrame code when embedding to google sites. I checked the submissions on some of your forms and I don't seem to notice any blank fields. If you are still encountering the blank fields, I suggest you try re-embedding the form to google sites and see if that fixes the issue.
