Sergey,

I wanted to ask you if I use your suggestion correctly, since I am getting strange results.

My SQL looks like this:
SELECT * FROM (cMyTableName) ;
	WITH (Buffering = .T.) ;
 	WHERE MYFLD = cUserEntry ;
 	TO SCREEN NOCONSOLE
The strange results I get is if the table has 1 record and I add another record with the same entry, the code above does not catch it. If I add 3rd record with the same entry, then the code finds the duplicate record. Can you think of why I get these results?

Thank you.
