JS drop down menu not working with frames....HELP!

[Rockrz]

I'm trying to get my drop down menu (javascript) in frame "A" to change pages down in frame "B"

If anyone with knowledge of how to do this could take afew minutes to help out, I would REALLY appreciate it. . . .



Up here is frame "A" & where
I've placed my drop down menu
_________________________________________


Down here is frame "B" & where I
want all my links to open into. I want to make
frame "A" stationary at all times



Here's the drop menu script I'm using

<script language="JavaScript">
<!--
function goToURL(form)
{

var myindex=form.dropdownmenu.selectedIndex
if(!myindex=="")
{
window.location.href=form.dropdownmenu.options[myindex].value;

// This is an alternative method you can use
// var frameTarget = "_new";
// window.open(form.dropdownmenu.options[myindex].value,frameTarget,"");
}
}
//-->
</script>


<form name="dropDownForm">

<select name="dropdownmenu" size=1 onChange="goToURL(this.form)">
<option selected value="">---------SELECT A PAGE---------

</form>


Here's the frameset script I'm using

<frameset rows="86,*" border="0" frameborder="0"
framespacing="0" bordercolor="#000000">
<frame name="header" src="header.html"
scrolling="no" noresize marginheight="0" marginwidth="0">
<frame name="main" src="main.html"
scrolling="auto" noresize
marginheight="0"
marginwidth="0">
</frameset>

<script language="JavaScript">
<!--
function goToURL(form) {

var myindex=form.dropdownmenu.selectedIndex;
if(myindex != 0) { // myindex is an integer
parent.frames.main.location.href = form.dropdownmenu.options[myindex].value;
}
return true;
}
//-->
</script>



By the way, the test (!somevar == <string>) is a different test to (somevar != <string>). It works if <string> is "", but more from luck than anything else.
