(This is a perfectly valid and acceptable question and I don't mean to censor it, but I'd just like to note for your future reference that the convention is to state it as an "Edit:" at the bottom of your downvoted comment, or in a direct reply to it. It makes it easier to figure out what you're referring to, for one.)

Your previous comment indicates that you did not read the other comments or the link in the OP. This is generally poor practice as it leads to redundant and uninformed commentary. That said, it probably would have been more appropriate to say so rather than just silently downvoting.
