myList.AddListItem(cField1)
myList.AddListItem( cField2, myList.NewItemID, 2 )

>How do I "omit nIndex"? I tried 0 but it doesn't work either! What I really want is for my list to work exactly as it says in the part of the help shown above. I have the Sorted property set to false and I want the items to be added to the end of the list.
