I am new to automator and am trying to get it to do the following:

read from CD drive each time a new disc is inserted

then find files containing xxxx

copy those files to folder xxxx

eject disk

I have the last three down but my problem is getting it to read from the cd drive each time. Here is a screen shot of what I have....

The very first drop down menu "where" is where I would need to set it but there has to be a specific cd in the drive. If you replace it with a different cd, it does not find the files. Any idea how to make it read from any cd or DVD in the drive?? Thanks!
