For www.domain.com/area/north

I can use:
RewriteRule area\/([0-9a-zA-Z_\&\-\ \.\/]+)$ home.php?areasearch=$1 [QSA,L]
to grab 'north' and pass it as a parameter to my home page

But now my url is more like:

http://www.domain.com/area/north/hom...ntshow=listing.....

I can't work out how to get at the 'north' bit without all the stuff afterwards

something like:
RewriteRule area\/([0-9a-zA-Z_\&\-\ \.\/]+)$\/([0-9a-zA-Z_\&\-\ \.\/]+)$ home.php?areasearch=$1 [QSA,L]
??

I know it should be simple, but I just can't get it to work!
Any help appreciated!
