jQuery.noConflict() is not working for popup box - html

Question

I am having a webpage with 3 slider and one popup box. For sliders i used jQuery.noConflict() so that is working fine. but in the case of popup box if i am using jQuery.noConflict() its not working.
If i am not using jQuery.noConflict() then my slider wont work.
popup html
<div id="popupContact">
<a id="popupContactClose"><img src="close.gif" alt="close"/></a>
<div id="contactArea"></div>
</div>
<div id="backgroundPopup"></div>
popup jquery
var popupStatus = 0;
function loadPopup(){
if(popupStatus==0){
$("#backgroundPopup").css({
"opacity": "0.2"
});
$("#backgroundPopup").fadeIn("slow");
$("#popupContact").fadeIn("slow");
popupStatus = 1;
}
}
function disablePopup(){
if(popupStatus==1){
$("#backgroundPopup").fadeOut("slow");
$("#popupContact").fadeOut("slow");
popupStatus = 0;
}
}
function centerPopup(){
var windowWidth = document.documentElement.clientWidth;
var windowHeight = document.documentElement.clientHeight;
var popupHeight = $("#popupContact").height();
var popupWidth = $("#popupContact").width();
$("#popupContact").css({
"position": "absolute",
"top": windowHeight/2-popupHeight/2,
"left": windowWidth/2-popupWidth/2
});
$("#backgroundPopup").css({
"height": windowHeight
});
}
var $rp = jQuery.noConflict();
$rp(document).ready(function(){
$rp("#buttonpop").click(function(){
centerPopup();
loadPopup();
});
$rp("#popupContactClose").click(function(){
disablePopup();
});
$rp("#backgroundPopup").click(function(){
disablePopup();
});
$rp(document).keypress(function(e){
if(e.keyCode==27 && popupStatus==1){
disablePopup();
}
});
});
Note: This popup jquery is an external jquery and i am using <script src="http://jqueryjs.googlecode.com/files/jquery-1.2.6.min.js" type="text/javascript"></script> also.
Thank you.

If you use jQuery.noConflict(), that prevents jQuery from aliasing jQuery as $. However your popup code is still trying to use $.
Either reference jQuery, not $, or wrap your code in a closure and reference $ as a local variable within the closure, i.e.
(function($) {
//popup code here
})(jQuery);
