I searched many time in this forum and help pages, but i don't find answer to my problem. I'm not a JavaScript guru, this is my biggest problem

I want to build a car (type-make-year-etc....) database from this site: http://toc.luk-as.de/
If i open this site loading available languages (with static URL), i select "English (GB)"
Loading a new site, than i want to select "Search via... / Vehicles" but in the Helium Scraper i can only browse. If i change to "Selection mode" than i can't select "Vehicles" (under Search via...) only can select "Search via..."
Please point me the right way.
Thanks
