As of right now, I have free shipping over a certain amount for everyone. However, I want to set up my site so that just orders in the US can have free shipping over a certain amount. International orders will be charged shipping on all amounts.

So, I created a new zone just for US. Then I went to the freeshipper module and edited it to reflect the lower amount and then selected my new zone. However, when I click update, a yellow circle displays (where is should be green) and the module doesn't work.

What am I doing wrong? I did a few searches on the board but couldn't come up with an answer.
