            while($table = mysqli_fetch_array($result)) { // go through each row that was returned in $result
            if($table[0] != "workers")
            {
                echo "<tr><p>"; echo("<td>". substr($table[0], 0, -3). "<BR>"); echo "</p></td>";   // print the table that was returned on that row.
        }
        $count = mysqli_query($link, &quot;SELECT COUNT(feedback) + COUNT(feedback_1) FROM `$table[0]`&quot;);
        while($cout = mysqli_fetch_array($count))
        {
            echo &quot;&lt;p&gt;&quot;; echo(&quot;&lt;td&gt;&quot;. $cout[0]. &quot;&lt;BR&gt;&quot;); echo &quot;&lt;/p&gt;&lt;/td&gt;&quot;; 
        }
        $countt = mysqli_query($link, &quot;SELECT COUNT(explanatory_1) + COUNT(explanatory_2) + COUNT(explanatory_3) + COUNT(explanatory_4) FROM `$table[0]`&quot;);
        while($couts = mysqli_fetch_array($countt))
        {
            echo &quot;&lt;p&gt;&quot;; echo(&quot;&lt;td&gt;&quot;. $couts[0]. &quot;&lt;BR&gt;&quot;); echo &quot;&lt;/p&gt;&lt;/tr&gt;&lt;/td&gt;&quot;; 
        }
    }

Ошибки в данных строках даёт:

while($cout = mysqli_fetch_array($count))

while($couts = mysqli_fetch_array($countt))
