Hi,

I have a spreadsheet with a column for "date entered", "order booked date"
and "lag" where "lag" is the difference between the "date entered" and the
"order booked date". This is a large spreadsheet and I need to take the
"order booked date" and "lag" and get an average weekly lag. I'm trying to
find a function or way to best do this without having to sort the "order
booked date", etc. The spreadsheet needs to be able to be manipulated by
other columns after.

Thanks for any help!
