WampServer

I was modifying my httpd.conf and did not save a backup. Now it seems to ignore my subdomains. I am probably missing something, but can anyone help? hosts file remains unchanged and has all localhost aliases added.

<VirtualHost 127.0.0.1>

I made the following changes to fix:

NameVirtualHost *:80

<VirtualHost *:80>
DocumentRoot "G:\wamp\www"
ServerName localhost
</VirtualHost>

<VirtualHost *:80>
DocumentRoot "G:\wamp\www\m"
ServerName m.localhost
ErrorLog logs/subdomain_error.log
</VirtualHost>

<VirtualHost *:80>
DocumentRoot "G:\wamp\www\careers"
ServerName careers.localhost
ErrorLog logs/subdomain_error.log
</VirtualHost>
