I was going to suggest checking to see if any errors are returned from MySQL after attempting to execute your query, as you don't appear to be doing this...

echo mysql_error($conn);

But I guess from your other thread [webmasterworld.com] that you are now inserting new user records into your DB OK? What was the problem?
