From: Fred Smith on 8 Feb 2010 22:32 The clearer the question, the faster the response, and vice versa. Things that help are the version of Excel you are using, and where the data is (column A, B, etc.). For this, I've assumed your start date is in A, and your end date is in B. For all entries in A, where there is no entry in B: =sumproduct(--(a1:a1000<>""),--(b1: b1000="")) Adjust the range to suit. For specific entries in A, with no entry in B: =sumproduct(--(a1:a1000=date(2010,1,1)),--(b1:b1000="")) Regards, Fred "js20217075" wrote in message news:38D25C25-E95D-4727-8ED5-1C5E4A2C4308(a)microsoft.com...> Please help!
