Hi Steve,
 
Thanks for your reply. I tired to change it to the following:
 

function getUserDisplayName($number)

{

$fieldId = 19;

$result = db_query("SELECT p.value FROM {profile_values} p WHERE p.fid = $fieldId AND p.uid = $number");

while ($nameQuery = db_fetch_object($result)) {

$displayName = $nameQuery;

}

return $displayName;

}

/**

* Implementation of hook_view().

*/

function blog_view($node, $teaser = FALSE, $page = FALSE) {

if ($page) {

// Breadcrumb navigation

$breadcrumb[] = array('path' => 'blog', 'title' => t('Blogs'));

$number = $node->uid;

$breadcrumb[] = array('path' => 'blog/'. $node->uid, 'title' => t(getUserDisplayName($number) . "'s blog");

$breadcrumb[] = array('path' => 'node/'. $node->nid);

menu_set_location($breadcrumb);

}

return node_prepare($node, $teaser);

}

But it still isn't working.
 
What am I doing wrong?
 
Sarah
