Why doesn't MAMP want to know about Virtual Hosts?

Question

MAMP

Such a disaster. Apache won't start on port 80. Works for 8888. In etc/hosts I wrote:
127.0.0.1 localhost dummy
Virtual Hosts:

<VirtualHost *>
 DocumentRoot /Applications/MAMP/htdocs/dummy
 ServerName dummy
 ServerAlias dummy
 <Directory /Applications/MAMP/htdocs/dummy>
    DirectoryIndex index.php
    AllowOverride All
    Order allow,deny
    Allow from all
  </Directory>
</VirtualHost>

If you open it as localhost:8888/dummy then it opens, if dummy/ then it doesn't. What could be the problem? I've been wandering around for a few hours now and I can't fix this issue...
