two dropdown lists - disable one from the other 2

[sickpuppy]

I am trying to use a form to pass through values to an .asp page.

I have 2 drop down lists and wish for the second to only be selectable depending on the value selected on the first.

Can anyone help?

sure:
[tt]
var first = document.forms[0].[firstSelectListName];
var second = document.forms[0].[secondSelectListName];

if (first.selectedIndex == [unacceptableValue]) {
second.disabled = true;
} else {
second.disabled = false;
}
[/tt]

if (!succeed) try();

function onOff(s) {
if (!s.options[0].selected)
document.f1.s2.disabled = true
else
document.f1.s2.disabled = false
}

<form name=&quot;f1&quot;>
<select name=&quot;s1&quot; onchange=&quot;onOff(this)&quot;>
<option>2nd ON <!-- the 1st option should enable 2nd select list -->
<option>
. . .

<select name=&quot;s2&quot;>

Setting the value of disabled = true or false doesn't work in Netscape, though. Anybody has any solution for this?
