Error loading page WP7

Error loading page WP7

When I try to change the page in windows phone simulator for example:

<a href="OutstandingBillDetail.html?id=1234"> </ a>
I get "Error loading page", do not know if it's because the url has parameters, but it should be working. OutstandingBillDetail.html page if it exists and is in the correct directory.

I need help, thanks!
