There is no value give to it initially, so I'm not quite sure what you
mean...
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.

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
}
?>
