Dada, one thing... We should use the getUniqeValue() because if we do dom manipulation and try the same code for service portal, it will give the error...

[@TheUkr1244]

Thanks for your efforts !!
In-Service Portal getting submitted without attachment also.
1. Alternate we have a checkbox in portal setting "Mandatory Attachment". on checking we cant submit without attachment.
2. On the Hiding "Add Attachments" button using "Hide Attachment" checkbox in portal settings and on adding the new variable type "Attachment" and we can make it mandatory.

I have written same as you written, but for me triggering error "Error MessageonSubmit script error: TypeError: gel is not a function:
function () { [native code] }". Please suggest how to clear the error

[@jktn1620]

Hi...
In place of this function -> var catalogsysid= gel('sysparm_item_guid').value; so you can use this below function in client script i.e var catalogsysid = 'sysparm_item_guid'.value; then you won't get any error

[@davejohnson392]

I am getting an error when I DO have an attachment:
Here is a copy of the Catalog Client Script:
function onSubmit() {
//Validate that an attachment has been attached
var catalogSysID = gel('sysparm_item_guid').value;
var checkAttachmentGA = new GlideAjax('CheckAttachment');
checkAttachmentGA.addParam('sysparm_name', 'attachmentCount');
checkAttachmentGA.addParam('sysparm_catalogsysid', catalogSysID);
checkAttachmentGA.getXMLWait();
var attCount = checkAttachmentGA.getAnswer();
if (attCount < 1){
alert('Please attach your passed Certification');
return false;
} else {
return true;
}
}
Anybody see I typo I am missing?
The code works if I Don't have an attachment so this is really strange.

[@SaudAhmed-jp5ic]

The error you are getting is because the gel() function is not available in Service Portal. This function is used in the classic UI, but it has been deprecated in favor of the g_form.getElement() function.
To fix the error, you can update the code to use the g_form.getElement() function instead of the gel() function. The following code shows the updated code:

If any applicable to help them pls give me solution to fix this code
