slideshow thumbnail issue

Hi, I am working on a WordPress site based on the avisio theme, and I cannot get the thumbnails below the homepage slideshow to link to the assigned pages; the url is on the bottom of the browser (chrome) when I hover over the thumbs, but clicking them does nothing. I have yet to get an answer from the theme developer, so I was wondering if anyone here could help me get the links working. I want the small thumbs od the houses to link to each house (the main images, which are set up as slideshow items, link properly. the thumbs are generated by the theme.): http://www.everbeta.com/tom/
