Stock Quote Sidebar Widget - CSS configuration?

Hello!

I am new to bothe wordpress and Atahualpa.

So, now I try to insert a Stock Quote Sidebar Widget. This widget comes with css file, but it is obvious, that it works with default one.

http://economicdisaster.eu/ - That's mine site - New widget is on left corner.
http://andy.hillhome.org/blog/code/stockquotesidebar/ - Here is the site of developer. You can see how it works on his site.

Thanks in advance!
