You may not be able to see anything in design view to edit, depending on the
PHP that is on the page. There is such a thing as a "process" page, on
which there is no presentational markup at all. In addition, there is such
a thing as a page that determines which markup to write "on the fly" - and
again, such pages would not have any presentational markup to edit in Design
view. Can you paste the code from the page into a reply here so we can see
what you are working with?
