CMS tutorial problem with sentry.php

[tyrc racing]

I have completed the tutorial thorugh to step 5 succesfully, and need help with this error I get upon logging in
Fatal error: Call to undefined function: getnumrows() in d:\users\tyrcuk\public_html\rc\includes\Sentry.php on line 65

what have I done wrong, or what can I do to change this?
