Quiery on formatted report based on multiple criteria

G

Grant

I am trying to create a report based on a database created with a realtime
database recording engine.

I would like to know (If it is possible - which I believe it is) how to
quiery the database file to do a calculation on two values in the first
column, that meet specified criteria in another column, dependening on a
matching value in another column.

If this does not make sense here is an example:

06:00.123 Yes Blue 01273
06:01.234 No Green 01243
06:01.345 Yes Red 01273

I would like to subtract the "time stamp" if Value1=Yes and Value2=Blue from
a "time stamp" where Value1=Yes and Value2=Red, Provided that Value3=01273
for both.

Any ideas?

Thanks
