If you are trying to pay for a purchase, does the seller ship to your Country, as unless the seller quotes postage to Sri Lanka you cannot pay.
I think that is what the confusing message you have received really means.
If this is the case then you need to contact the seller and ask for a revised invoice showing the correct postage.
