Thanks, Joel. I'll give it a try. I have a huge number but it will be worth
setting it up this way. Many thanks. Norm.

I have several worksheets with stock symbols listed according to various
criteria. I want to find the symbols that are common between the worksheets
or some of the worksheets - for example, common in 2 out of 4 sheets or 3 out
of 4 sheets.

Is there a way of doing this. I am using Excel 2007

Many thanks. Norm.
