location is a reserved word, so try this:<SCRIPT LANGUAGE=javascript>
function go() {
loc=document.form1.menu.options[document.form1.menu.selectedIndex].value;
target=document.form1.menu2.options[document.form1.menu2.selectedIndex].value;
if (target=='blank') var win = window.open(loc);
else location.href=loc;
}
</SCRIPT>

dosn't "blank" have an underscore before it? (_blank) or is that html?

It does have the underscore in front but in this case it doesn't really matter as the script posted as a solution is using window.open for the new window rather than just setting the forms target to _blank besides in HTML Strict and XHTML Strict the target attribute has been deprecated because it was considered a behavior. Since JS is good at behaviors we use js to create the new windows.

Fwiw, it does make a difference.

As in markup, the second, target argument of the window.open method functions similarly to the target attribute in markup.

e.g.
window.open('blah.html','blank'); // one reusable window

window.open('blah.html','_blank'); // new window every time
