I created the following array in Excel 2007 and it works fine.

I then save the spreadsheet to be compatable with 2003 and when I open the
file the data is there, but any changes to the data or the array and the cell
goes blank.

Is it possible that somethign in the formula is incompatable with 2003?

Thanks in advance for any help.

=IF(ISERROR(INDEX('Roll Cleaning Data'!C:D,SMALL(IF(cleaning_status="
",ROW(cleaning_status)),ROW('Roll Cleaning Data'!1:1)),2))," ",INDEX('Roll
Cleaning Data'!C:D,SMALL(IF(cleaning_status="
",ROW(cleaning_status)),ROW('Roll Cleaning Data'!1:1)),2))
