:-(

Elation turns to deflation. I don't understand. Everything worked fine. I'd commented out the bad code and done the good, like I copied to you (see below). And it worked great. Then I went back and got rid of the old code and ran it again. It's now taking JUST AS LONG and is reporting EVERY record.

Can you see anything wrong with the code below?

Thanks

Terry
