🚀 go-pugleaf

Thanks a lot jongware..now its selecting the objects correctly but i m struck with adding to the group and duplicating the group.
I tried the follwing code but it didnot work.

main();

function main(){
	if (app.documents.length != 0){
		if (app.selection.length > 0){

			var myObjectList = new Array;
for (i=0; i<app.selection.length; i++)

	myObjectList.push (app.selection[i]);

alert ("length of myObjectList is "+myObjectList.length);

var myGroup =app.documents.groups.add(myObjectList);

var myGroup1=app.documents.groups.duplicate(myObjectList1,myObjectList1);

				}
			}
		}

I know i m asking silly questions but i m a begginer to this scripting and want to learn more.Please guide me with the proper code to do so.

Thanks,
Sanat
