Graziano,
Please do not PM me with requests. I offer to help and distribute code but I will not offer individual consultations. Especially considering what I am about to say.
You applied this code a few days ago. You are now asking me to explain why you don't have more pages in Google.
Simply put, WAIT. If your site merits the indexing (i.e. fits Google's criteria) it will be indexed as much as it merits indexing.
It takes more than days and sometimes more than weeks. As your PR improves Google will want to index more of your pages.
I will add other techniques to this tutorial/MOD but I'm not going to answer the now already overwhelming "tell me why Google hasn't indexed more pages" requests.
You guys are asking me by PM (and I do not provide support by PM) and asking me while expecting Google's indexes to update within days.
In the past Google updated around once a month.
Google has two types of updates, freshbot updates and deep crawls.
We just finished a deep crawl (seep crawls are getting rarer but still exist).
You may have to wait till the next crawl. Google has no schedule for this but over the last few years it has averaged once a month.
So do not ask me about results a few days after you make a change. It's simply pointless as your change will not necessarily be immediately reflected in Google.
If you want instant gratification submit your site to
www.gigablast.com that is the only search engine of decent size that features live indexing (e.g. submit a URL and a few minutes later it's in the search engine).
