Hi Bernard and thank you for responding. I found a formula yesterday which
enabled me to find the latest/max date within a range and subject to a
criteria. This formula was: =sumproduct(MAX(--(A:A=A1)*B:B)). So I thought
I could use this to find the first date/min. However, because there are
blanks agains some criteria these are picked up as the minimum values.

I am therefore hoping there is something I can do the the sumproduct formula
above that will skip the blanks and give the the first date against a
specifed criteria with multiple dates.

If this is not enough info. I will send you an example spreadsheet if that
pos.

Thanks again

This finds the minimum value in the A range subject to the corresponding B
value being "a". But if there are two cases you get twice the answer.
=SUMPRODUCT(--(A1:A16=MIN(A1:A16)),--(B1:B16="a"))

Can you please expand on your problem. You want to find the minimum value of
PO1 with the proviso that the date in also in the range Created1? With named
ranges we cannot see the whole picture. For example what is the size of each
range?

best wishes

I am trying to find the minimum date in a range, which contains blanks.
subject to a criteria. As the range contains blanks, these are currently
picked up as the min date and display 00-Jan-00.

Is there a way of using sumproduct and excluding/ignoring blank cells?

PO1 is my range for criteria and Created1 is my range on the dates I am
using in the following formula

=Sumproduct(MIN(--(PO1=A2)*Created1))
