JQuery Working in Plain Text File, but not WordPress

Hi,

I have this jquery code which is working fine when i run it from a plain text file, but it won’t work in wordpress. Any ideas?

I am loading the jquery 1.10.1 library.

https://code.jquery.com/jquery-1.10.1.min.js

var $j = jQuery.noConflict();
var linkAnchor = $j('#link-apartment-guide');
var randShareLink = Math.floor(Math.random() * 5) + 1;
$j(document).ready(function(){
    if (randShareLink === 1){
    linkAnchor.append('case1');
    } else if (randShareLink === 2){
    linkAnchor.append('case2');
    } else if (randShareLink === 3){
    linkAnchor.append('case3');
    } else if (randShareLink === 4){
    linkAnchor.append('case3');
    } else {
    linkAnchor.append('case4');
    }
});
