/***********************************************************
doDelete is used to delete the form from the server

The user is first asked to confirm that this is what they
want to do. Giving them the chance to cancel the action.
This works SIMPLY by changing the end of the URL from 
"?OpenDocument" to "?DeleteDocument"
