If you want to mirror the French part you should try to add
the address of each frame :
<http://10.reverse41.fmcf.fr/polefgm/index.htm>
<http://10.reverse41.fmcf.fr/polefgm/french/marge.htm>
<http://10.reverse41.fmcf.fr/polefgm/french/accueil_fr.htm>
<http://10.reverse41.fmcf.fr/polefgm/french/menu.htm>
<http://10.reverse41.fmcf.fr/polefgm/french/logo.htm>

then add the adresses of the parts of the site which are
missing when clicking on the menu.

if it works you can do the same with the English part if you
need it.
