Coding to move from one site to specific part of another site?

Question

Forgive if I am not explaining this very well- here goes. I have one major site with three other gallery sites that are related. From one of the gallery sites I need to create a button that takes you back to a specific page on the major site. Playing with the coding has not resolved the issue so appreciate any help in finding magic:
on (press) {
    getURL("http://www.client's main site.net","_blank");
gets me back to the beginning of the major site but I need to get to a certain page within the site. Is this possible? Thank you! All coding is AS2, Mac platfom, FlashCS5.

Answer 1

if you want to load frame 22, use:
on(press){
getURL("http://www.yoururl.com/page.html?framenum=+22","_blank");
then within the head tags of page.html in yoururl.com, use:
<script type="text/javascript">
function urlF(){
return location.href;
</script>
and in the swf that's embedded by page.html, add the following to frame 1:
import flash.external.ExternalInterface;
stop();
trace(ExternalInterface.call("urlF"));
//  upload that to your server, post the url to the flash containing the getURL() and indicate which button needs to be pressed.
