Don't have time to totally disect it, but you might change the if($num_rows)
to if($num_rows 0) just to make sure.
Also, try echoing out your SQL statement to check and make sure things like
$table got a real value or other silly things.
Lastly, I usually use single quotes for SQL statements.. in this case, it would
simplify your PHP SQL statement by removing the necessity to escape all the
double quotes \
If you echo the SQL and it looks ok, try running it manually through mysql's
command line or via a program like WinSQL Lite on Windows to try to isolate if
it's the query or your PHP.
Good luck!

I am trying to write a script to handle event registration. Most of the
people that will be registering are already in the database, but not all,
and those that are may not have current information.
Here is my latest effort, or at least a snippet of it... Can anyone point
out where I went stupid, or if there is a better way of doing this?
THANKS!!!
