Adding extra amount to flat shipping base on pincode

[srivats]

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 ...

[srivats]

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.
