Problems with Virtual Hosts on MAMP

[stonefree]

I am not able to use more than one virtual hosts at a time on my MAMP testing server. Here is the excerpt from the end of my httpd.conf file -

Syntax: [ Download ] [ Hide ]

Syntax: [ Download ] [ Show ]

NameVirtualHost *

<VirtualHost *>
ServerName edmazursf.com
DocumentRoot "/Users/stonefree/Sites/EdMazur/"
</VirtualHost>

<VirtualHost *>
ServerName cleantechms.com
DocumentRoot "/Users/stonefree/Sites/CleanTechMS/"
</VirtualHost>

and my hosts file

Syntax: [ Download ] [ Hide ]

Syntax: [ Download ] [ Show ]

127.0.0.1 http://www.edmazursf.com edmazursf.com
127.0.0.1 http://www.cleantechms.com cleantechms.com

The problem is that the second host, cleantechms.com will point to edmazursf.com 's site (while keeping the original URL) .But if I comment out the first host and restart MAMP, cleantechms.com will work properly

Can someone tell me what I'm doing wrong?
