Hi,
I am very new here. I need a help from guru of scripts.
Recently, I am trying to use chainedselectmenu code from Xin Yang and DD.
However, I couldn't show the search result at different page. I mean , using frame, search part at top part and result part at bottom part in one page. Then I can search again without usie backward button. So fa just use the code from DD as a source The source from DD works well - search and refresh the screen and show the result - however , I need to modify them for my page. Please help me. I can not modify the code to show 2 page in one screen. Followings are the code from DD, work well

<code chainedselect.js >

var _disable_empty_list=false;
var _hide_empty_list=false;

var onclickaction="open"

function goListGroup(){
for (i=arguments.length-1;i>=0; i--){
if (arguments[i].selectedIndex!=-1){
var selectedOptionvalue=arguments[i].options[arguments[i].selectedIndex].value
if (selectedOptionvalue!=""){
if (onclickaction=="open")
window.location = selectedOptionvalue
else if (newwindow==1)
window.open(selectedOptionvalue)
else
window.location = selectedOptionvalue
break
}
}
}
}

///// END DynamicDrive.com added function//////

if (typeof(disable_empty_list)=="undefined") { disable_empty_list=_disable_empty_list; }
if (typeof(hide_empty_list)=="undefined") { hide_empty_list=_hide_empty_list; }
...

I think need to modify the DD added part to show 2 page in one screen with frame set.

Thanks.
