hello i have installed the flate rate clone its working with googlecart, i have made a clone of the clone so that i know have 3 flat rates, theproblem i have is that google check out picks up the flat rate price for the first flat rate price,

in googlecheckout.php i see
$this->shipping_support = array("flat", "item", "table", 'freeoptions', 'freeshipper', 'perweightunit', 'storepickup', 'itemnational', 'iteminternational');

i have called one of the clones flatworld and i have tried adding "flatworld" into the array but i just get a oops error in the google checkout can any one help me with this thank you
