looks like you hit it on the head. If you don't have $Apache::DBI::DEBUG=1 in your startup, then you wont see anything in the errorlog. from the doc: "To enable debugging the variable $Apache::DBI::DEBUG must be set. This can either be done in startup.pl or in the user script." -- Michael Peters Developer Plus Three, LP
