Hi All,
Well, I've continued investigating this further and my findings are as
follows.....

1. When concatenating fields using rules you cannot put in newlines,
you can only do this through code
2. You cannot have both code on a button click event and also have a
"close the form" rule on the same button, this in IP client stops the
code from executing; but in forms server it makes the web page get
stuck and displays a msg saying "Form Closed" and at the same time a
looping message saying "Form Loading".... weird...
3. It is possible to trigger a submit from code, but not a save or
close form
4. You can clear the errors buffer and therefore remove all validation
errors from a form through code

Based on the above findings the only (watch out this gets nasty)....
way that I can see to implement a custom submit button which ignores
validation is as follows.....
1. Create your button that executes your code and clears the errors on
a view
2. Make this button also through code switch to another view eg: one
called say "Closure"
3. On this new view have a nice big button called "Close me now" (with
a rule to close the form), and the user clicks this to close the form.

this is an extremely nasty and non-user friendly solution, please
please please can someone help me find a solution that works and is
nice and friendly to the user???
Surely Infopath is better than this???

thankyou very very much
cheers
