Could you please help me to fix the Solution for the below script (Catalog script validate attachment)

Error MessageonSubmit script error: TypeError: gel is not a function:

//Type appropriate comment here, and begin script below

var catalogsysid = gel('sysparam_item_guid').value;

var ga = new GlideAjax('CheckAttachment');

ga.addParam('sysparm_name','attachmentCount');

ga.addParam('sysparm_catalogsysid',catalogsysid);

Hi @Khaled RAJHI ,

You can replace the gel function with document.getElementById. Here's the modified version of your script:

function onSubmit() {
   // Get the catalog sys_id value using document.getElementById
   var catalogsysid = document.getElementById('sysparam_item_guid').value;

   // Create a new GlideAjax object
   var ga = new GlideAjax('CheckAttachment');
   ga.addParam('sysparm_name', 'attachmentCount');
   ga.addParam('sysparm_catalogsysid', catalogsysid);
   
   // Call the server-side script synchronously
   ga.getXMLWait();

   // Get the response from the server
   var attCount = ga.getAnswer();

   // Check if attachment count is less than 1
   if (attCount < 1) {
      alert('Please Attach your Passed Certification');
      return false;
   } else {
      return true;
   }
}
