Harry, I just posted this in another discussion in which you participated, but I’ll repeat it here. I have tried to donate a few times using my tablet (iPad) and PayPal. Each time at the end of the process, after completing the captcha, I get a message to the effect that I must “fill in an amount other than zero.” I have specified a donation amount prior to getting to that point. It happened again today, twice, after I was reminded by this discussion that I should try again. I’ll try later with a credit card, but I thought I’d let you know in case this is preventing others from donating via PayPal.
