Donation in USD

I'm trying to donate, but the donation methods are all in Euros. I tried the form anyway but I keep getting a "Transaction Unsuccessful" message. Is it because I trying to donate in USD? Is there another place for me to donate in USD?

Thanks for the help.

Your credit/debit card should automatically convert to the proper currency with a minor transaction fee. Are you trying to use another form of payment?

Thanks for the reply. It looks like it was my bank not approving overseas payments. Thanks again!
