Thanks very much for the input. This did something, but it did not seem to do the trick. Before the change, we would input a zip code and the screen would refresh, but the shipping would not calculate. Instead, the "Enter your Zip code" input box would remain. Also, after we enter a zip code, the shipping drop down box disappears, and the follow shows up "To calculate shipping costs, please proceed to step one of checkout. anonymous."

Now, after Boomer's suggested change, X-cart seems to get the zip-code entry (because it gives the "To change your zip code click here" option), but it does not calculate shipping. Also, once you have entered a zip code, the "To change your zip code" option is dead--it does not actually work.

Our troubleshooting shows:
X-Cart IS getting the zip code (it is changing zipcode_estimate)
X-Cart IS setting "default country" to "Y"

Any thoughts?
Thanks!
