Hi everyone, I'm having real problems with the shipping element of Zen Cart, I am using zen cart version 1.3.8 with an Apache/PHP Unix system. I have added the following mods and I wonder if one of these might be causing the problem Dymo label printer and diable (or disable) registrationlogin

I have zone rate by weight enabled and it works fine with the shipping estimator but then when in checkout it gives a much higher postage cost. I have 3 zones - zone one is the zone for GB, zone 2 is for EU and zone 3 is the rest of the world. the shipping estimator correctly estimates at zone 1 but the checkout seems to be quoting zone 2. Does anyone have any ideas how I can fix this problem? Any help would be greatly appreciated
