    Can I restrict a text field to not allow commas?

    Asked by glumber on August 21, 2015 at 04:10 PM

    Hello. I have a Company Name text field and don't want to allow a visitor to use a comma (,) as part of the naming. Is there a way to do this? Thanks.

    Thank you for contacting us.

    We cannot block specific symbols, but we do provide some validation options. For example, you can try an AlphaNumeric validation.

    The validations seem to be not working properly on your embedded form due to jQuery and Prototype JS conflict. Please try adding the next jQuery noConflict script as shown on the following screenshot.

    <script type="text/javascript">

    If you need any further assistance, please let us know.
