errorHandler()
Used by Netscape to return the error message to the user.
Best used only when debuggind in development. Turn on by 
adding the following line to a form:
if (navigator.appName=="Netscape") window.onerror = errorHandler;

doDelete is used to delete the 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
