Declare var win outside of the function.

<script language = "javascript">
var win;
function popup()
{
win = window.open("HelpFile/alert.htm", "Help", "width = 500, height = 300, top = 50, left = 450, scrollbars = no, resizable = no");
}
</script>
<body onunload = "if (win &&!win.closed){win.close();}">

No prob, cLFlaVa, I'm just experiencing an onrush of questions after two weeks of very difficult school lol

Hmm... It should work. Try this:

if (Help && !Help.closed) {Help.close();}

But before should work. Make sure that your popup opens before you close.
