0r share your full client script screenshot

Yes I checked mark that.

Here is the full screenshot:

we use following script

function onSubmit() {

  try { //Works in non-portal ui

  var attachments = document.getElementById('header_attachment_list_label');

  if (attachments.style.visibility == 'hidden' || attachments.style.display == 'none' ) {

  alert("Please be sure to attach all required documentation prior to submitting your request");

  return false;

  }

} catch(e) {

  if ((this.document.getElementsByClassName('get-attachment').length == 0)) {

  alert('Please add the required attachment before submitting this request.');

  return false;

}

}

}

Hi Vladimir,

Thank you but I tried it and it didn't make the attachment mandatory.

Instead of:

attachment.addQuery('table_sys_id','sys_id');

could you please try with:

attachment.addQuery('table_sys_id',sys_id);

Also, please check this thread: Catalog service making Mandatory Attachment both application and SP
