if(isset($_POST['deleteme'])){

        $count = count($_POST['multiple']);
        $data = $_POST['multiple'];

        for($i=0;$i<$count;$i++){
            $id = $data[$i];
            mysql_query('delete from multiple where id='.$id);
        }
    }

<td><input type="checkbox" name="multiple[]" value="<?php echo $result['id']; ?>"/></td>

Try this

<?php
include("db_connect.php");
extract($_POST);

if (isset($delete))
{
for($i=0;$i<count($delete);$i++)
{
$sql="delete from cekla where noC='".$delete[$i]."'";
$result=mysql_query($sql);
}
}
header("location:test1.php");
?>
