Run-time-error 1004 "ListIndex method of listbox class failed"

[Fan924]

I am getting Run-time-error 1004 "ListIndex method of listbox
class failed"

It stops at
ListIndex = RowNo ' Error
using excel 97. It was written in excel 2000 and works fine in 2007. I
was testing it with 97 and it I get this error.
I changed From
.ListIndex = RowNo
to
For .ListIndex = 1
Still fails. Is this one of those commands that did not exist in this
for in 97 version.

What type of listbox is it?

The code shouldn't really work in any version of Excel, ListCount is a
count of the items in a listbox.

The index of a listbox is zero-based, eg item 1 - listindex = 0, item
2 - listindex etc...

So there is no item with the index equal to the ListCount, the last
item's index is list count minus one.


Try this:

For RowNo = 0 To .ListCount-1

or

For RowNo = 1 To .ListCount
....

..ListInde = RowNo-1
