Prices suddenly in Euros?

For some reason, prices on my modular pages are showing up in Euros or something ( € ? ) now where they were (and should be) in dollars. WTF? Is there a new setting that I need to change somewhere? I'm in the US.

There should be a link below each price that lets you toggle back and forth between euros and dollars. I'm guessing you accidentally clicked on it?

Looks like that was it. Thanks.
