Thank you for reaching out to me regarding your IABC membership. As I don't have your email address, I'm replying on the Ning network, hoping you will read my email. I have checked with the President of IABC Belgium, Colin Hensley, and our treasurer, Benedictus and it is not possible to pay in euros. The credit card payment will be in dollars and then charged into your account in euros.
Dick had similar problems in the past, usually when trying to use an American Express credit card.
In the case the online procedure fails, I suggest you print out the renewal form, add your credit card details, signed it and mailed it to headquarters.
Let me know if you manage to complete the payment.
We will host IABC Summer drinks after World Conference, will post it on the Ning.
