this should be:
document.form1.select2.options[document.form1.select1.selectedIndex].value);

> alert("test2 is : " + document.form1.select2.options
> [document.form1.select1.selectedIndex].value);
> alert("test3 is : " + document.form1.select1.options[index0].value);

You have no value attributes in your option tags. So, it's working, but you
can't tell.

Oh, oh, please stop banging your head. You're gonna dent your desk up.
