[Resolved] Display name not Username

[krysttof]

In my functions.php, I have this code :

PHP Code:

if (file_exists(GSUSERSPATH.$data_index->author.'.xml')) {
    $data = getXML(GSUSERSPATH.$author.'.xml');
    $NAME = stripslashes($data->NAME);
} 


In my template.php file, I have this code :

PHP Code:

<p>Auteur : <?php echo $NAME; ?></p> 


Nothing is displayed and I have two errors :

PHP Code:

Notice: Undefined variable: author in /Users/mymac/Sites/gs-site/theme/mytheme/functions.php on line 51
Notice: Trying to get property of non-object in /Users/mymac/Sites/gs-site/theme/mytheme/functions.php on line 52 


The line 51 : $data = getXML(GSUSERSPATH.$author.'.xml');
The line 52 : $NAME = stripslashes($data->NAME);
