I'm struggling with what you really need here ...
Are you saying you want read/write/execute permissions on every file/directory below www?
if so, here one way - perhaps the most straightforward way:
chmod -R ogu+rwx www/store
$ find .
.
./www
./www/store
./www/store/1.cgi
./www/store/1.html
./www/store/2.cgi
./www/store/2.html
./www/store/3.html
./www/store/4.html
./www/store/5.html
$ ls -l www/*
total 0
-rwxrwxrwx 1 lji None 0 Jun 30 11:34 1.cgi
-rwxrwxrwx 1 lji None 0 Jun 30 11:32 1.html
-rwxrwxrwx 1 lji None 0 Jun 30 11:34 2.cgi
-rwxrwxrwx 1 lji None 0 Jun 30 11:32 2.html
