jQuery Forum

I am trying to incorporate two javascript files (using jQuery) and they are creating a conflict. If the main js is on the page part of the page does not work. If I do not include it my menu and some related features do not work correctly. I do not have the site on a live server for you guys to go and look at yet I can post the JS code here for you.

I am really new to javascript/jQuery and could use a little help. Can anyone see a obvious conflict and help me combine the files to work as one without the conflict? Thanks!

One code is long so here is the link to it: *I removed Link* (this is the main code for the menu etc)

The other js is: 

$(document).ready(function(){
    Engine.Initialize();
    if( !$('body').hasClass('index') && !$('body').hasClass('homepage') ) {
    }
});

var Engine = {
   
    Initialize: function() {
        Engine.Homepage_Animation();
    },
   
    Homepage_Animation: function() {
        if( !$.browser.msie ) {
            $('#homepage-main-item img').hide().fadeIn(700, function(){
                $(this).css('display', 'block');
               
                $('#homepage-boxes .boxes').each(function(i) {
                    $(this).delay(100 * i).animate({
                        opacity: 1
                    }, 300);
                });
            });
       
        } else {
            $('#homepage-main-item img').css('display', 'block');
            $('#homepage-boxes .boxes').css('opacity', 1);
        }
    },
   
    }
