I caught that error, but the line number was referring to the assignment, it
didn't even get to the obvious error.

Why would $total = $db->affected_rows, (assigning the value of
$affected_rows to $total) be interpreted as a method call?

I have since defined a num_rows() method (using mysql_num_rows()) and I have
gotten past this error, however I am still having a major problem with what
I'm trying to accomplish.

I'll post more later tonight when I get home from work... Thanks for your
help Thijs adn Darren
