How do I create a formula that only brings back the number of days for
each
unique Accession number? For instance, Accession #EH52212995 took 1 day
to
process, but there were three different test ran, I only need to know that
it
took one day. HELP.


Accession Unit Code MColDt Collect Date MRecDt Received Date Report
Date "Days to
Process"
