    dw,

    Looks like you're trying to access the wrong window. Suggestions:

    1. Trying using *self* instead of *window*
    2. Does *opener* indeed refer to the window in which *window.open()*
was called?
    3. Per D. Flanagan: "This property is valid only for Window objects
that represent
top-level windows, not those that represent frames."

    If you continue to have trouble, please post a link to the frameset
page in question.

    Thanks.

    Sorry, but that last bit, while a commonly-held belief, is FALSE.

    I happen to care little for VB or VBS, so nearly all my ASP work has
been done in
JScript, which is supported in MS PWS/IIS/ASP/WSH.

    I don't mean to sound belligerent or anything like that, but it
really irritates me that
so many people believe ASP=VB when it's not true. Both VB(S) *and* JS
are supported by the
*default* IIS/PWS installation on all 32-bit Windows versions. (BTW, if
you install
ActivePerl on your server, you can do your ASP code using PerlScript.
And client Windows
systems which have ActivePerl installed can run clientside PerlScript in
MSIE 3.01 and later.
You should be able to do the same with Python once ActivePython is
released.) If you're
interested in exploring ASP using JScript, I'll be glad to point you to
some references on
it.

    TRUE.

jacek,

The answer is "Yes". Try looping through the Option elements, checking
the *selected* value
of each:

function reportAllOptions(selectObj)
{
    var output="";

    for(var i=0;i<selectObj.options.length;i++)
        if(selectObj.options[i].selected)
            output+="Option #"+(i+1)+":
"+selectObj.options[i].value+"\n";

    alert(output);
}

(Test it yourself with this:

<form>
<select name="mySelect" multiple="multiple" size="5">
<option value="larry">Larry</option>
<option value="joe">Joe</option>
<option value="moe">Moe</option>
<option value="curly">Curly</option>
<option value="shemp">Shemp</option>
</select>
<br />
<input type="button" value="Click me."
onClick="reportAllOptions(this.form.mySelect);" />
</form>)

HTH!
