Need help with GET parameters

[eluser]Unknown[/eluser]
Hello,

i have a problem. When I use url http://127.0.0.1:8884/creator/article/index/0/?lng=eng, ir gives me this error ERROR - 2010-02-06 11:49:22 --> 404 Page Not Found --> lng. But why is it opening a page lng? It should open index, and use lng as a simple GET param.
