USPS from Canadian Origin?

[dimsumgurl]

I was able to get this to work with zencart 1.3.9 version and the Canada post module and USPS to work at the same time giving quotes

Now Im trying to upgrade to 1.5.5 and this trick to change the SHIPPING_ORIGIN_ZIP in includes/modules/shipping/canadapost.php to the postal code while in admin/config/shipping and packaging to the zip code, it doesn't work...

What can we do?

Thanks!

Actually it's working now... all because I switched to a different template.... I was recently using Tableau 2... but switched to Carlisle Fresh.
