Image GK4 didn't show after compression JS

Hi, I found several post for the same questions, but no one give a perfect answer. If I turn off the JS compression, the page speed give my web 64 points, If turn on it's 84. I wish any one can give a solution for it.
It's seems the error take by
window.addEvent('domready', function() {

SqueezeBox.initialize({});
SqueezeBox.assign($$('a.modal'), {
parse: 'rel'
});
});
var K2SitePath = '/';
var k2storeURL = 'http://honortrack.com/';
window.addEvent('load', function() {
new JCaption('img.caption');
Thanks in advance.

Hi

I think the only solution is to exclude this file from compressing. This is a conflict which takes place while scripts are present in one file, so probably there were a noConflict statements between them, but was removed because of another occurence of the same statement. So maybe changing the order of loading script will help but this is not the easiest way to do.
