This could be tricky
Most online charity donation forms are set up with payment gateways based in the UK.
In our experience most of them only seem to accept British pounds Stirling through their webforms.
This shouldn't be a problem if you live in Europe though, as you can still donate but you'd have to trust your bank to apply a fair exchange rate.
The only other option might be to try and write or call the charity but if this turned out more expensive than what you might lose in a bank applied exchange rate, we think it might be best to just donate online.
