  It worked for me.  Did you type the code in verbatum to what you have showing above?  If so, check your double quotes.  If not, then I believe it's something in your environment setup.   ;  Yes, that should absolutely work. Just fix your double quotes; the source you posted reveals a lot of them as HTML entities instead.
