[A bit OT but not] Anchors and Query strings

I need to set up a link that has both. However, IE/NS isn't liking this: www.mydomain.com/thispage.php#joe?thisvar=thatvalue I need to pass "thisvar" into thispage.php and use it to determine information to display. I also need to pass the anchor name "joe" so the page jumps down to that anchor. What am I doing wrong? Also, I need to parse the above to get information for something else. Is there any easier way to get "joe" out of the above than a regex? Chris
