How should I set formatDate?

[Miwa]

hi Brian,

I found this

How to get date with st nd or th using formatdate

Here a custom formatter that uses moment.js for formatting the date. Place following script in a js file or script block: dmx.Formatter('string', 'formatDate2', function(val, format) { return moment(val).format(format); }); Now use it like: {{ next_birthday.formatDate2("dddd, MMMM Do YYYY") }}

and tried the following with setting formatter,

but it doesn't work...other guys could use this formatter though, I don't know what's wrong..
