Flexigrid - Lightweight but rich data grid

[eluser]hating[/eluser]
I have table that contain edit links( for editing records) Than i want to have "Back" button that load on page that was before editing.
I try use next, but it's didn't work:
1) generate page with next flexigrid changes
$("#flex").flexigrid({
<<< skipped >>>
page: &lt;?php echo $_REQUEST['page']; ?&gt;
total: &lt;?php echo $_REQUEST['total']; ?&gt;
rp: &lt;?php echo $_REQUEST['rp']; ?&gt;
<<< skipped >>>
});

2) after all write something like
$("#flex").flexOptions({page: "&lt;?php echo $_REQUEST['page']; ?&gt;" });
$("#flex").flexReload();

Thank you
