How to add banknotes for swap

Hit "My Account"

You should hit the BOTTOM 2nd link (below) so you can view just the countries you've entered:

Once you find the banknotes you wish to swap, you'll want to edit your listing:

It will then show the box "irruig" has posted, and you can change to "yes" for exchange.

thanks for your clear replies. It's all understood
