need help on my selectbox multiple

[pixeltrace]

guys,

 

i need help, i have a selectbox in my update form

 

items on my selectbox will be taken from the database

and from the update form you can re-select other items and have it update

 

my problem now is, i can't make it work, i use implode and i am getting some errors

implode()function implode: argument to implode must be in array

 

how do i fix this?

below is the code for my selectbox

                    <select name="specialization[]" size="8" class="field3" multiple="multiple">
                     <option value="<? echo implode("\n",$specialization); ?>" selected><? echo implode($specialization); ?></option>
				  <?
				  include 'db_connect.php';
$uSql = "SELECT specialization FROM specialization ORDER by sid ASC";
$uResult = mysql_query($uSql, $connection);
if(!$uResult){
echo 'no data found';
}
else{
while($uRow = mysql_fetch_row($uResult)){
?>
                      <option value="<?= $uRow[0]?>">
                      <?= $uRow[0]?>
                      </option>
                      <?
    }    
}
?>
                    </select>
