Aoife,

Array enter, using Ctrl-Shift-Enter:

=MIN(IF(B2:B100="",A2:A100))

Format for date, and change the range to reflect your data range.

Two columns: A & B
Column A = delivery due date
Column B = delivery date
If no delivery is made, cell is left blank.

How can I get Excel to return the oldest missed delivery date?

Thanks for any suggestions in advance.

Aoife.
