Is there a way for me to count in a column and exclude numbers that repeat? I am working a spreadsheet with account numbers and need to count how many account numbers...the problem is that some of them repeat within the spreadsheet. Can someone help??

Thanks in advance!

I don't know why this works, but I use it on one of my docs.

OK, first hightlight the entire range of cells that include the account numbers. I'm hoping they are all in a single column. With the cells highlighted, click on INSERT > NAME > DEFINE. In the popup that appears, type AccNums and click ADD.

You've just "named" all your account numbers and can use that name in a formula. Here is the formula:

This formula should result in the number of how many unique items it found in the range. It should also ignore blank cells.
