"Invalid procedure call or argument"
As I try to remove an item from a listbox call List1 I try this code...

If List1.List(i) = List1.List(i + 1) Then List1.RemoveItem (i)

if the list contents are identical, remove one of them
but it doesn't work!

Hi,
Can you try this one if it works for you.
For example you are trying to compare the column 1 of your list1.
if list1.listitems(i).subitem(1)=list1.listitems(i+1).subitem(1) then
list1.listItems.Remove 1

hope it gives you an idea.
