Hello.
First of all set your main store www.choozeonline.com
For the second store make sure perfumes.choozeonline.com is pointed to the same path. Check this in your hosting cPanel
You are asking me to remove http before www in my main store? When I save store, http is automatically populated in the field. See JPG.
My sub domain is in same directory, Please See JPG.
If I write store/ at the end of sub domain of perfumes then still its not working and displays error:-
Not Found
The requested URL /store/ was not found on this server.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
