I am working on a query that calculates a the average of the difference between two dates.
The issue I am having is that there are some pieces of occasional data that can severly skew this average, so I don't want to include them. So I would like to have the query ignore data where the field that causes the skew is null.
As a truncated example, I'm using:
IIf([Transferred]=True And [Legal Hold Off]=Null And...
but as soon as I add the Null parameter, my query returns nothing. The proper syntax must be simple, but I'm stumped!!
