Hello @Ammad Satti,

I'm not sure to understand..

I have created a "Catalog client scripts" with this code :

function onSubmit() {
	var value =  g_request.getParameter('IO:84dabf301bd1689097ce31e5464bcbc2');
	guide.add(value);
}

I took a sys_id of one of my catalog item for example.

And i have this error :

One other question, how can i get the sys_id of my order guide variable "Catalog Items" and put it on this script ?

Thanks for your help. 🙂
