If the dates are in ascending order you could use VLOOKUP
VLOOKUP(G2,$A$2:$B$1000,2,FALSE)
since it will return the first match it finds

Otherwise
=MIN(IF($A$2:$A$10=G2,$B$2:$B$10))
this is an array fromula and must tbe entered with CTRL+SHIFT+ENTER not just
ENTER
Once you have it in H2 you can copy it normally down the column

I have an initial customer list A2:A1000 and the Dates each customer
called
in with a question B2:B1000

from that list I have created (using advanced filtering) a unique List
(G2:G100)

A2:A1000 are of course not all unique customers, as the same customer
could
of called in any number of times through the year.

However using my Unique list (G2: G100) I would like to get the first date
in which this customer called and nothing more and display it in the cells
H2:H100


I am using excel2007 but it needs to be backward compatible with 2003.

Any suggestions
