Finding Duplicate Rows
I have a worksheet with a detail tab and a summary tab. In column A on my
summary tab I have a list of values. What I want to do is look these values
up on my detail tab and see if they exist more than once. If they do I just
want to return a value of "1" in column B on my summary tab. Some of these
values are a combination of text and numbers. How would I write this formula?
