[RudhraKAM]

I have a requirement where i need to check if the catalog item have 2 attachments , if not it should not submit , 

i am able to check the attachment by using on submit client script on the catalog item but how and where to include the count ?

Can some one help me with that 

function onSubmit() {
//Type appropriate comment here, and begin script below

var proof = gel('sysparm_item_guid').value;
var att = new GlideRecord("sys_attachment");
att.addQuery("table_name", "sc_cart_item");
att.addQuery("table_sys_id", proof );
att.query(att);
if (!att.next()) {
alert("Please include the attachments");
return false;
}
return true;
}

Hi @Mike Patel ,

You can try with this code:

var proof = gel('sysparm_item_guid').value;

var rowcount=0;
var attachment = new GlideRecord("sys_attachment");
attachment.addQuery("table_name", "sc_cart_item");
attachment.addQuery("table_sys_id", proof);
attachment.query();
while (attachment.next()) {
rowcount++;
}
//alert("Row "+rowcount);
if(rowcount <= 2)
{
alert("message");
return false; 
}
else
{
return true; }
}

this line: 

var proof = gel('sysparm_item_guid').value;

is not working for me, why so? I'm applying it to a record producer and to my understanding gel('sysparm_item_guid').value refers to current CART item in the order guide, where CART means it is being used for a catalog item rather thatn a record producer
