URGENT: PHP & database errors

I *think* this would not be that difficult to solve, by someone who has more time than I do. I have an install of Drupal 4.7 that I am testing. There is some custom PHP code embedding in a page that looks to an outside custom application, with a database called "events." For some reason, Drupal is spitting out errors because it is looking in the events database for the watchdog table (rather in the Drupal database). I have attached a screenshot of the errors.
