How to flatten a completed form after submit?

Question

I am creating a form in Acrobat 9 and would like the form once submitted to us as a "PDF The complete document" to be flattened so no changes can be made. This filled inform is an agreement that must be saved in the customer file.
I have tried the javascript to flatten the form within the submit button. It works to freeze it on the customer end, but when I receive it back via email I have an interactive form again.
I really need the form to be completely flat so no erroneous changes can be made when received from my customers.
Another problem, If you have a script to pick up the current date in your form the flatten script will not flatten the date. Every time the submitted form is opened the date changes again.
Anyone have any ideas for me?

You appear to high jacking the OP's post.
You have to identify the products the users filling in the form will be using. Only Acrobat or maybe some other full feature editing program can dynamically change a script using the setActiion or addScript methods.
That means you need to figure out another technique to prevent the update. The easiest test is to only change the date field if it is empty. But this means the saved copy of the form that is distributed must have the date field empty when distributed.
You do not want users to use Apple's Preview application!
If there are mobile devices involved, you need to test on each platform and with each app that will be used because not all mobile device apps support JavaScript within PDF forms and many do  not support forms at all.
var cDateField = "MyDateField";
if(this.getField(cDateField).value == "") {
// date field is empty so we fill it in;
cDate.value = util.printd("d-mmm-yyyy", new Date());
} // end fill-in date field;
