Question regarding startup scripting

Hi all

I am trying to put some code into my Siebel application that will check a date in a BC and if the date is older than another date redirect the user to a different starting view than his defined Startup View.  I have played around in the Application_Startup event but I cannot get the gotoView method to work, in fact the application doesn't even startup correctly with this code active.  Does anybody have any ideas on where/how I might achieve this?

Thanks in advance
