Without any clues to work with, its difficult to say what the problem might be..
Possibly, your version of out.php lacks the line ..
$ID=$_GET['ID'];
Or.. possibly the combination of Apache/PHP you use makes this line ..
$REMOTE_ADDR=$_SERVER["REMOTE_ADDR"]; result in an empty variable.. or maybe that line is missing.....
Just copy paste this out.php over the top of your current one..

if that doesn't help.. please try to describe the problem in another more detail.
"it doesnt work" doesn't help me to help you.. How doesn't it work?
What does it do? Is any error message shown at all? Perhaps your web server writes errors to an error log instead of displaying them ?
