In the code below the phrase Welcome <Name> will appear every time because you have it appearing outside the if statement.  If you are getting the Welcome message along with the "Sorry, no login for <Name>" message it means that revdb_recordcount is working.  Just delete the line right after get revdb_query and then only the message that you expect will show up.
