For form name (single line of text), the user can not type a text exceeding 260 characters and for&nbsp;the attachment, the user can not attach a file with too long file name exceeding 260 characters as well.&nbsp;I am not sure how to&nbsp;customize error messages for these two fields when the user takes an inappropriate action?&nbsp;I wonder if there is best approach for this settings to make the form more user-friendly. Any suggestions are greatly appreciated! &nbsp;:-) </p>
