Why might the gallery script not work in IE?

Question

Gallery

We made a two-level gallery for the site. Example: astron-mebel.ru/photo/comp/1/3

When you select some pictures, photos of details appear on the right.

For some reason, when you first click on the link, the photos are not shown at all. I do a refresh - everything works.

Versions of IE - 8 and 9.

How to be?

Answer 1

SCRIPT438: Объект не поддерживает свойство или метод "jcarousel" page_ini.js, строка 417 символ 4
The plugin must be loaded before it can be used in code. During a refresh, the plugin is taken from the cache and has time to load before being used.
