Worksheet function?

[Guest]

Hello,
I would like to write a worksheet function which compare the contents in two
cell from a database1 with the contents in two columne in database2.
Whenever there is a match I would like it to return a a prespecified text
(i.e Yes or No)and a value from database2 associated with the found match in
cells of database1.

Empty cells in database1 (in one or both the cells where comparasions values
are found) also needs to be considered as no comparasion should be made (i.e.
do not return the text Yes/No for the first match with any empty cell in
database2).

Anyone that has suggestions?

Kind regards
Jonas

This looks like a Vlookup function but with two lookup cells. A way to do
that is to concatenate the pairs of cells in a new column and use that in
your lookup, i.e. if the first cells in database1 are in A2 and B2, insert a
column at C and type in it the formula =A2&B2 and copy it all the way down.
Do the same in datbase2 and then you can use an ordinary Vlookup because
you've now only got one cell to compare.
