Adding extra amount to flat shipping base on pincode

[srivats]

I want to add extra amount to flat rate shipping based on buyer's pincode.I stored extra amount in session.But when i tried to add that amount in flat.php,its not working.

$this->quotes = array('id' => $this->code,
                            'module' => MODULE_SHIPPING_FLAT_TEXT_TITLE,
                            'methods' => array(array('id' => $this->code,
                                                     'title' => MODULE_SHIPPING_FLAT_TEXT_WAY,
                                                     'cost' => MODULE_SHIPPING_FLAT_COST +$_SESSION['postage_fee'] )));

Any ideas??

If you add above that code:

echo 'Postage Fee: ' . $_SESSION['postage_fee'] . '<br>';

what value do you see?

Are you sure that the:
$_SESSION['postage_fee']

is being set properly? Is it a number, like 1.25 or characters like $1.25 ...

It has $ sign with number.

The number sign makes it characters or a word and a word is worth $0.00 ...

Change it to a number only with not characters or commas etc.
