[AccessD] Query giving different results each time

Mark,

Any possibility on sending that table to me? If so, zip it up.

wow...ok...I still don't understand why I would get different results from 
the same sql...but I'm ok with that for now...

Scott, the sql below and the 2 query approach did give different 
results(about 300 difference).

The sql below did give the number I expected...but as Patricia pointed 
out...it did not always give the max of the date...although it provided the 
correct number of records...they were not always the correct ones...So I 
tried to change the 'last' on the effdt to 'max'...but the results do 
vary...I get the last phone number...but the max date...with this approach 
the date and phone don't necessarily correspond anymore.

So close...I can feel it.

Thanks,

Mark
