Button to Convert from Dynamic to Static form Attach to Email then Convert Back

Question

I have this working, but only on reader 9. What I need is a different way to accomplish this. The scenario is I have a dynamic form that we fill out for a customer. We want to email it to a customer, but we don't want them to have access to our calculations.
So I want a button that turns the dynamic form into a static form than attach the static PDF to an email, than I want it to change back to dynamic on the original.
This works in acrobat reader 9, but not in reader 7.
my code for the submit button is this
for (var nPageCount = 0; nPageCount < xfa.host.numPages; nPageCount++) {
var oFields = xfa.layout.pageContent(nPageCount, "field");
var nNodesLength = oFields.length;
// Set the field property.
for (var nNodeCount = 0; nNodeCount < nNodesLength; nNodeCount++) {
oFields.item(nNodeCount).access = "readonly";
that code works fine in acrobat reader 7 and later, the problem comes in when I switch it back to dynamic with this code in the postsubmit event
for (var nPageCount = 0; nPageCount < xfa.host.numPages; nPageCount++) {
var oFields = xfa.layout.pageContent(nPageCount, "field");
var nNodesLength = oFields.length;
// Set the field property.
for (var nNodeCount = 0; nNodeCount < nNodesLength; nNodeCount++) {
oFields.item(nNodeCount).access = "open";
This nets me an error on opening the form in any reader previous to reader 9:
Invalid enumerated value:postSubmit
Anyone have any ideas?
If there is a way to do this in formcalc I would rather do it that way, because there are a few fields I'd like to hide before the customer gets it as well.
Thanks

Well, I don't know, but one might suspect that one of these times when the DNG converter gets upgraded (and it does from time to time) one of the things that might happen is that at some point Nikon might free up all its proprietary stuff in a NEF and that would be available to Adobe to include in an upgrade.
Hmmmm, in that case it might be worthwhile to reconvert NEFs--but that would mean redeveloping all those digital negatives.... Whoa....maybe I better stop this line of reasoning before I really upset you and others who have converted from NEFs. You are discovering some of the reasons why I don't do that just to save a little space--and be free of sidecars, of course (a noble motive, for sure).
I do convert for other shooters who are clients, but I always store the NEFs and DINGs and derivatives together in the same folder, which of course raises storage loads, but that is the way they want them.
Try the DNG UtoU forum. There are some very knowledgeable guys over there.
