Thanks for the info, it works! Now how do I find out more about flags. This would be fantastic improvement to the process, whereby as soon as a particular section is filled out, the form knows to be automatically emailled to someone else.
The flag is a programatic way of telling your server side program what to do. The flag can be what ever you want it to be. Simply set up an invisible field (so th euser does not see it). Then set a value in it (that your server side code will use). Once you submit the data, your server side will check the value of the flag field and act accordingly.
Hope that helps
