Greetings,

I have one sheet which contains a status, date received, and a date
completed.

I would like to be able to calculate the average number of work days between
date received and date completed where the status is equal to quot;closedquot;.

I have figured out a not so slick way by adding another column to my sheet
and calling the networkdays function on every row.

I'd like a more elegant solution where I can look across the entire range
and calculate the average number of networkdays where the status is equal to
quot;Closedquot;.

I tried average(networkdays(received range:closed range)) for starters but
the networkdays function doesn't want to take a range of values......

Help/Suggestions welcome....
