Warning: array_sum() [function.array-sum]: The argument should be an array in pdf.php on line 112

i am getting this error and i dont see what the problem is. it calls values and adds them

$result = mysql_query("SELECT * FROM sold_produce WHERE invoice_id='$invoice_id' ");
        while($myrow = mysql_fetch_assoc($result))
             { 
  $total2[] = $myrow['total'];
	}
	$content .= array_sum($total2);

$result = mysql_query("SELECT * FROM sold_produce WHERE invoice_id='$invoice_id' ");
$total2=array();
        while($myrow = mysql_fetch_assoc($result))
             { 
  array_push($total2, $myrow['total']);
	}
	$content = array_sum($total2);

sorry the code i had was fine. it was that a variable was hiding that over wrote what i had previous. i hate it when i ask for help and then i find what the problem was after
