I understand. I'm looking for a way to load a page from the cache and
modify it from within the script. The problem I have is that apparently
the page doesn't get loaded until I exit the script. I am/was looking for
a way around it.

The only thing I can think of is to modify the page when I submit the
form, so if I return to it I'm in the 'edit mode.'

The difference between normal and edit modes is that in the normal mode,
the form is submitted to the next page in order, whereas in the edit mode
the form is submitted to the final page. There are six pages of data entry
and a final report page. I want to return to individual pages in the edit
mode from the final page and return to the final page after editing so I
don't have to re-enter the data on subsequent pages.

I can, of course, mark a page to be in the edit mode when I submit it the
first time, but the guy entering data could conceivably realize he made an
error and use his browser's back button to return to correct the problem,
and then submit the corrected data only to find that he skipped over empty
pages to get to the final page.

Yes, I could provide instructions to not do it, but I'm trying to make my
app damned-fool proof.
