Can't get AJAX paging to work.

I'm a beginner with Drupal so this may be something really simple, but I've been struggling with it for a couple of days now.

What I'm trying to accomplish: I'm trying to create a small list of announcements, which will display three items at a time, and will have "previous" and "next" buttons for people to page through them all. It's important that the "previous" and "next" buttons don't cause the page to refresh.

To that end, I have a view that's set up to display the Post Date & Title of recent announcements (3 at a time), filtered by Node:Published, Node:Type, and Taxonomy:Term. I've turned on paging, and set "Use AJAX" to "yes". When I look at the preview of the view, the AJAX paging works like a charm, however when I embed the view in a page, the AJAX doesn't work - in other words, the pager buttons force the browser to reload the page.

This particular view has a "Block" display, which I embed into my page's .tpl.php file using this code: print views_embed_view('announcement_pager', $display_id = 'block_1');

I've also tried displaying the view using the admin/build/block interface. The view shows up fine this way, but the AJAX still doesn't work.

I've tested this in both Safari and Firefox, with and without Javascript enabled, and both while logged in and logged out. It's the same each time.

Like I said, I'm a beginner with this, so I don't really even know what kind of additional info would be helpful for troubleshooting this. If anyone has specific questions about what I'm doing, let me know. Thanks in advance!

Oh, and here's my exported View:

$view->api_version = 2;
$view->disabled = FALSE; /* Edit this to true to make a default view disabled initially */
