Not really an error. Don't worry about that. As it says it is only a
Warning.
If you set error_reporting to 7 or something below 15 (all) those warnings
will disappear. The reason why your attempt with ELSE didn't work is that
the variable is not created if the checkbox is not checked. So to achive
what
you want use isset()
if (isset($CatONE)) {
echo "One!!";
} else { // if $CatONE is not set == not existant
echo "No Type set!";
}
hope it helps
