twentyten excerpt not working???

Hi guys,

I know that a lot of people has already asked this and I’ve seen a lot workarounds but for some reason I can’t get the excerpt to work :(.

So I have the twentyten theme and on the loop.php on line 137 I’m changing this <?php if ( is_archive() || is_search() ) : // Only display excerpts for archives and search. ?> to this <?php if ( is_archive() || is_search() || is_page(2) || is_page('blog')): ?> and yet the posts keep showing in full under the page blog page_id=2. Unfortunately the site is in my localhost so I cannot leave a link.

Also on ‘Settings -> Reading Settings’ I have the following:
Front Page displays – A Static page (Front Page:Home, Posts Page:Blog)

For each article in a feed show: Summary

If I click in one of the ‘Categories’ (menu column on the right) I see all the posts related to that category with the excerpt (only 40 words are displayed) but once I click on the Blog menu button it takes me to the Blog page and displays all the posts in full.

Anyone can help? Pleaseeee
And I do apologise for posting this again but I’m going nuts 🙁
