That's what I was trying to do with the ListSort() function.

The problem is that when you start your loop the array is 7 elements long, you delete the first and the array is now only 6 long , but your loop still thinks the array has 7 items. The trick is to loop in reverse, from the end of your array *down to* the first item. This way you are never trying to delete an item that dosen't exist. Hope this helps. -eric ----- Original Message ----- From: <[EMAIL PROTECTED]> To: "CF-Talk" <[EMAIL PROTECTED]> Sent: Sunday, September 30, 2001 4:08 PM Subject: Using CFLoop to delete from an Array > I have a form that will allow users to randomly select items to remove from > a form.
