Hi, I'm getting a script error having something to do with a class in IE 5.5. I know absolutely nothing about Javascript. Here's my code:

<SCRIPT LANGUAGE="JavaScript1.2" TYPE="text/javascript">
var tellafriend
function TellAFriend() {
self.name = "MainWindow";
tellafriend = window.open('http://www.mysite.com/tellafriend', 'choose','width=445,height=320')
tellafriend.focus()
}

</SCRIPT>

Can you tell me what's wrong? Thanks!
