simple line break

Hi all,

I have a simple question I am calling a title and category description which works fine thanks to some forum help, but I would like to put a further line break between the title / description as it currently appears like this:

http://www.magic-photography.co.uk/?cat=14

where the title just goes into the rest of the text. I have tried using nl2br; but can’t get it to work. Here is the code:

<?php
  if (is_category()) { single_cat_title(); nl2br; echo category_description(); }
  elseif (is_tag()) { ?>  posts tagged "<?php single_tag_title(); ?>" <? }
  elseif (is_day()) { the_time('F jS, Y'); }
  elseif (is_month()) { the_time('F, Y'); }
  elseif (is_year()) { the_time('Y'); }
  elseif (is_author()) { the_author(); }
?>

Thanks in advance
