Good question, Steve. It made me do some research, since I haven't used encryption yet professionally. I did notice a few minor errors: the field name should have been Sales, not SalesValue, and the third and fourth options appear to be missing a comma, so they probably wouldn't pass the parser, even if there was a function by that name. However, these are minor quibbles that don't really detract from a good question. Thanks! 🙂
