Post code error on checkout

In the shopping cart address fields, after I hit register it takes me to the next page and it shows all the filled in information in the fields, except for the post code that is blank? How can I fix this so it is viewable?

Could you give a link to your shop so that we can see the problem ?

www.germfreetoothbrush.com you have to enter the billing information and then hit next to see the confirmed address without the post code

I attached a screen print

here is a screen print of what I am talking about

I can see that you're not using the default address post code for a new custom field that you created.
In that case, you should edit the address_template files of the front end and back end to add a tag for your new post code field.
However, I don't understand why you're not using the default post code field ?

the default wasn't working either, that is why I tried to create a new one, but that didn't work.

That's strange because it's working for every one else.

So were you able to display it with the address_template files modification ?
