First: Thanx Brad, the select works now that I downloaded the nightly=
build.
Second: I immediately ran into another problem. The next page in the=
series basically just propegates the inputs forward "On Load" to another=
page through a javascript function that calls location.replace. I wrote a=
quick example to show you what happens.
Page1.html
-------------------------------------------------------
<HTML>

alert("Selection =3D '" + selection + "'");

document.forms[0].submit();

What happens is that I get an output of Output_Page1.html and=
Output_Page2.html from the test where Output_Page1.html should be the same=
as Page1.html and Output_Page2.html should be the same as Page3.html,=
however Output_Page2.html is instead the same as Page3.html.
Thanks again for the help.
Regards,
John S. Atkinson
