TWO Slide Panels need to toogle one at a time - need help.

Question

I have installed TWO slideDown panels. Please see my website: link text

I only want one panel open at one time. How do I make so that if one panel is opened the other will close automatically?

Here is my current code:

$(document).ready(function() {

$("#open").click(function(){
$("div#panel_quote").slideDown("slow");
}); 

$("#close").click(function(){
$("div#panel_quote").slideUp("slow"); 
});  

$("#toggle a").click(function () {
$("#toggle a").toggle();
});  

$("#open").click(function(){
$("div#panel_login").slideDown("slow");
}); 

$("#close").click(function(){
$("div#panel_login").slideUp("slow"); 
});  

$("#toggle a").click(function () {
$("#toggle a").toggle();
}); 

});




<script type="text/javascript">
$(document).ready(function(){

$(".btn-slide").click(function(){
$("#panel_quote").slideToggle("slow");
$(this).toggleClass("closeQ"); return false;
});


});
</script>

<script type="text/javascript">
$(document).ready(function(){

$(".btn-slide2").click(function(){
$("#panel_login").slideToggle("slow");
$(this).toggleClass("closeL"); return false;
}); 


});
</script>
