PayPal donation issue

Hi
I have a question in regrds to my form.
We use the paypal “donate button” on the form.
I thought the donate button charged no fees.
I just made a test payment of 1 pound and it charged 23 pence.
Can you help me wiht this. thank you

I'm afraid this is totally beyond our control. Please see this PayPal forum post. If there's anything else with which you need assistance, we'd be glad to provide it.

Thanks
