Truncating Excerpts Dynamically

 i couldn't make this work- may have to do with

$recent = new WP_Query("cat=27&showposts=1"); while($recent->have_posts()) : $recent->the_post()

i wonder if i replace that with

<?php if (have_posts()) : while (have_posts()) : the_post(); ?>

hmmm...

i emailed the author and asked where he placed the code within the loop. he said it should work just about anywhere.
