If you have register_globals OFF, it might appear to never get set to 1, because it's in $_POST['NextCourse'] not in $NextCourse Your else() above isn't valud syntax... Perhaps you should post EXACTLY what your code looks like... > value of document.form1.NextCourse.value. > > could someone tell me why?thanks This could probably be done easier, by the way, by just using: <input type="submit" name="NextCourse" value="Click me if there is another"> and then: <?php if (isset($_POST['NextCourse'])){ //They clicked the button to indicate another } else{ //They clicked some other button } ?> -- Like Music? http://l-i-e.com/artists.htm
