Joining Joined Tables - El Forum - 10-27-2014

I am stuck in generating SQL statement for joining tables.
Basically I have 4 tables. And there are 2 tables with foreign key. Table Sequence is connected to Product table and Region Table. And Distribution table is connected to sequence table.
Table Products.
id | product_desc
Table Region.
id | region_desc
Table Sequence.
id | product_id | region_id
Table Distributions
id | sequence_id | sales | distribution_fee
Here's my code
Code:
$this->db->select('*');
$this->db->from('distributions');
$this->db->join('sequence', 'sequence.id = distributions.sequence_id', 'left');
$this->db->join('sequence', 'sequence.product_id=products.product_no'); //Generates Error
$this->db->join('sequence', 'sequence.region_id=regions.id'); // Generates Error
$this->db->order_by('distributions.id','asc');
$query = $this->db->get();
if($query->num_rows() != 0){
return $query->result_array();
} else {
return false;
}any help is highly appreciated. Thanks.
