@Rick Rothstein
your code looks like very handy to me, because it has the option to
choose only the rows I want to check
But...I can't make it works properly
Please, Let me know more about it!

I may have misunderstood what you are looking to do. I took your example as
gospel and code my macro to look **only** in Columns A, B and D, but in
re-reading your original message, I'm not so sure you want the columns being
looked at so restricted. Can you clarify exactly what is to be searched? If
not just Columns A, B and D, but rather all columns, then is the order of
the items important?
