Default Problem with Master Page PostbacURL property

Ive made a page application.aspx which inherits trader.master... Now in the trader.master masterpage file Ive added a menu control which compulsarily needs a form to run... Now I cannot add a form in application.aspx as it gives me an error

Page can have only one server-side form element.

So im stuck with using the form on the master page... but when I use the postbackURL="~/applicaationprint.aspx"... I suppose it should postback the data to applicationprint.aspx

now in my applicationprint code behind file:

Code:
        string appno = Request.Form["ApplicationNummberTextBox"].ToString();
        ResultApplicationNumber.Text = appno;
Gives me a

System.NullReferenceException

all the time.. It does not pass variables at all....

It works fine if I remove the masterpage.

Please Help
