Hi, I have doubts about what you are trying to do will even compile. I suggest you take a look at the puppet docs on templating to get a clearer picture: http://docs.puppetlabs.com/guides/templating.html
and after that you should take a look at variables: http://docs.puppetlabs.com/learning/variables.html That should make some things a little clearer for you.
