I understand i have to use an array formula, but I don't know how!

I have an array listing dates when products arrived from diffferent
countries. I want to produce a chart which shows the number of arrivals for
each month from each country. COUNTIF will produce a total of arrivals for
each month, or a total from each country (ie for one condition) - but how
about for two conditions - this country in this month?

=SUMPRODUCT(--(TEXT(A1:A100,"mmm")="Jan"),--(B1:B100="Mexico"))

as an example

If you mean a particu;ar month that you select (assume december 2004)

=SUMPRODUCT(--(MONTH(A2:A100)=12),--(YEAR(A2:A100)=2004),--(B2:B100="this_country"))

or if you mean the present month according to your computers clock

=SUMPRODUCT(--(MONTH(A2:A100)=MONTH(TODAY())),--(YEAR(A2:A100)=YEAR(TODAY())),--(B2:B100="this_country"))

Thanks Bob

Trouble is the data are extracted from a data base and one record represents
an item - includes date received and country of origin. List is in the order
of 3000 records, and i want a summary chart with dates (all 1st of month in
'Jan-03' format) down left side with list of countries (as column header)
across top. the number in each cell shoul equal the number of items received
from that country in that month. Summary should change if country name is
changed.
