I have a really complicated issue. I am looking to count the number of unique phone numbers in a date range, for a unique inbound 800 line. So one column Sheet2!O:O contains the phone numbers and another column Sheet2!K:K contains the date ranges, and Sheet2!I:I contains the unique inbound 800 line. I am looking to display this total on another page using the Sheet 2 references. Any idea how I can do this? I already figured out how to total by date ranges and unique 800 line but this is a little more complicated with the unique values for unique phone numbers.
