Screen Scraping Still Not Working

I have browsed through many posts on this and have tried some of the suggestions but still not understanding it fully. I would like to scrape html pages that have some script running that usually executes the script to display a link after clicking. Some mentioned firebug and others talked about reverse engineering the code I need. But after trying reverse engineering I still dont see how to get the data after tracing the script function.[code]I am using vb.net and some sites were easy using firebug where looking at the script I was able to pull the data that I needed. What woudl I do in this scenario? the link is url... and the categories are what I am trying to access. Notice the url does not change.
