Manglende data

Hej

Jeg har dette udtræk:

***********************************

<table width="430" border="0" cellspacing="0" cellpadding="0"><?

    $query = mysql_query("SELECT punchLine, articleText, filename, url FROM articles_articles WHERE articleID='$articleID'") or die(handleError(mysql_error()));
    $row = mysql_fetch_array($query);

    echo "<tr>";
        if($row[filename]) {
                echo "<td width=100><img src=../images/articles/".$row[filename]." width=95 height=70 border=0></td>";           
        }
        else {
            echo "<td width=100><img src='../images/articles/noImage.gif' width=95 height=70 border=0></td>";
        }
            echo "<td width=330 valign=top class='bodyText'>".$row[punchLine]."</td>";
    echo "</tr>";
    echo "<tr>";
        echo "<td>&nbsp;</td>";
            echo "<td>&nbsp;</td>";
    echo "</tr>";
    echo "<tr>";
        echo "<td>&nbsp;</td>";
            echo "<td valign=top class='bodyText'>".$row[articleText]."</td>";
    echo "</tr>";
    echo "<tr>";
        echo "<td>&nbsp;</td>";
            echo "<td>&nbsp;</td>";
    echo "</tr>";
    echo "<tr>";
        echo "<td>&nbsp;</td>";
            echo "<td valign=top class='bodyText'>LINK</td>";
    echo "</tr>";
 
?></table>

***********************************

Hvis der er et filnavn i "filename" i databasen, vises alle data som de skal, men hvis feltet er tomt i databasen vises ingen af disse

$row[punchLine]
$row[articleText]

Meget mystisk synes jeg...
