Index.php

$breaking_num = "4";

/* Number of recent posts to display under the Breaking News */
$latest_num = "18";
/* IDs of any cats you dont want to include in Recent posts.
Start each ID with a 'minus' symbol Seperate by a comma & space.
EG: $latest_ignore = "-7,-6,-8,-1";
Posts from the 'Breaking' category are automatically excluded. */
$latest_ignore = "";
?>


<!-- Show x Posts from Breaking News -->

while (have_posts()) : the_post();
