[SOLVED] Joomla 1.5 + VM 1.1 lightbox broken

[feuerfest]

------------------
someone already advised me to cut out all lightbox, slimbox js + css from template
------------------
Hi,

on my page:
http://www.jouel.com.au/dev/index.php?page=shop.product_details&flypage=flypage.tpl&product_id=17&category_id=7&option=com_virtuemart&Itemid=61

something went horribly wrong with the lightbox. I cant figure out what is wrong, probably too much JS or CSS files are included, maybe someone can help me figuring it out.

Thanks
