I have 3 views in a InfoPath file that is connected to a MS SQL Data source

The three views are :
1) Start View
2) New Entry View
3) Edit/Delete Entry view

The Start View has only one field (call it BoxNumber).  When I hit submit on
Start View, I query the database for that BoxNumber and if the database
already has the entered BoxNumber, then I would like to be in the Edit/Delete
Entry view.  If the entered BoxNumber is not in the database, then this is a
new entry, and I would like to be able to go the the New Entry View.

The part that I am having difficulty with is dynamically selecting between
the 2nd and 3rd views based on the user input in the 1st view.

Any help in regards to this is greatly appreciated.  Thanks much!
