Can anyone tell me what is wrong with the Gem purchasing page?

I was surprised to see the currency in Euro on the Gem purchasing page. I usually see the prices in USD (I am in Ireland) However when I pick a Gem package the checkout page does not come up and I can’t go any further. I am left with a blank page. I have tried Google Chrome, Internet Explorer and FireFox. I thought I would have got lucky on one of them but no such luck.
