Query strings and indexing issues

[jremsen]

I already made a SEO for a site, set the robots.txt and sitemap file properly.

Time after, some changes were made to the site and pages were changed to public access. I changed the sitemap file and the robot.txt file to allow access the new pages and disallowed older ones, one of the allowed pages was a dynamic site that load information depending on an id parameter sent through the query string.These changes to the robots and sitemap files were made more than a month ago but google doen't recognize them; the pages disallowed are still shown by google and the other pages, specially the one with the query string, seems to be invicible.

I set up the querystring page this by the way:
Allow: mypage.php?*
Allow: mypage.php?id=*

I also tried just allowing one of them by there was no effect.

What am I doing wrong?
