Drop down menu arrows

yo… i’ve got this drop down menu… but i’d like to know if there’s any way to change “scroll bar” properties for the ‘pull down arrow’ ??

here’s the drop down menu:

 
<!--DropDown Navigation-->
<script type="text/javascript">

<!--
function jumpForm( obj )
{
if ( obj.options[obj.selectedIndex].value == '1' )
{
iframe.location = 'start.htm';
}

if ( obj.options[obj.selectedIndex].value == '2' )
{
iframe.location = 'info.htm';
}
if ( obj.options[obj.selectedIndex].value == '3' )
{
iframe.location = 'projects.htm';
}
if ( obj.options[obj.selectedIndex].value == '4' )
{
iframe.location = 'links.htm';
}
 
}
//-->

and here’s the css i have for the other scroll bars on the page where the d.down menu is placed:

 scrollbar-base-color: whtie;
scrollbar-Face-Color: white; scrollbar-arrow-color: #999999;
scrollbar-Shadow-Color: #222222; scrollbar-DarkShadow-Color: white;
``` and here's the css i have for the other scroll bars on the page where the d.down menu is placed: ```php scrollbar-base-color: whtie; scrollbar-Face-Color: white; scrollbar-arrow-color: #999999; scrollbar-Shadow-Color: #222222; scrollbar-DarkShadow-Color: white; ``` </SCRIPT>
