Postback URL not working - posting back to itself ?

Hi I am trying to post values in a text box to a new page (page2.aspx) But for some reason the postback URL is not working and the form is just posting back to itself Can you see what is wrong with this (I can't) It works when test on my local machine but not when posted to the web     <asp:button id="Button2"       text="Post value to another page"       postbackurl="page2..aspx"       runat="Server">     </asp:button>
