Phil,
Besides just turning off Warnings, the warning is a tad valid. Here's what I learned
when I spoke with some gurus at the php conference...
They said that the proper way to test for the presence of a variable now is using the
isset (or empty) functions. If you do the old way like I used to do:
if($variable){
then do this
}
and variable doesn't exist..you'll get a warning pop up if you've left them on. The
proper way to test for a variable is to say:
if(isset($variable)){
then do this
}
or
if(empty($variable)){
then do this
}
check the manual on php for the difference in those two, they can be quite useful.

That's just a warning not an error mesage. Change the error_reporting in the
php.ini
to E_ALL (I think it is) or put error_reporting(7) on top of the scripts.
