Hi Ron,
Probably I'd suggest something like...
a) wrap the session value in the header in a div;
<div id="sOwner"><!-- Net:s:Owner--></div>
(Because the Net:s: no longer appears in the header once it's served, just the data, so if you want to update the data you'll need a way to identify it.)
b) In the form, on the Server side code; something like (not tested)
p_web.script('$("#sOwner").html("' & somenewvalue & '")')
Cheers
Bruce
