If anyone else is wondering why formula evaluation is not working in Chrome, it is because jsfiddle is violating Chrome's security policy by serving up the javascript from fiddle.jshell.net (not jsfiddle.net). When this javascript code attempts to access the LocalStorage API, Chrome (rightfully) steps in and says: nope. This may be a new security feature, but is present in Chrome 30.0.1599.114 on Fedora.
