Thanks for this however I'm afraid this is not quite what I'm after.
The above formula will get rid the entry if either of the dates are blank. I however am interested in these entries and only want the entries with TWO blank dates to leave the report.
E.g if I have a date 1 and date 2 and they are the same - not on report.
if i have date 1 missing and date 2 missing - not on report
if I have date 1 and date 2 missing - on report
if I have date 2 missing and date 1 - on report
if i have date 1 and date 2 but they are different - on report.
Hopefully this makes more sense?
Thanks again.
