I chose my address in the drop box and after I clicked it was ok it now says "Please select an address or create a new one. I put a second one in my profile but it won't let me choose another one. How can I give my address to the other person to send my cards?

Could you give us a link to the trade in question please, and let us know which internet browser you are using?

What happens if you select an address from the dropdown (on the trade page) and click on Confirm?

I chose my address from the drop down and confirmed it then it said that and won't let me choose anything else.

I'm using firefox.
