I was wondering if anyone has created a character countdown for multi-line boxes in Forms (version 9.2.1). I've got a multi-line box with a limit of 1500 characters. I have help text under the box letting the user know they can only type a max of 1500, but it would be nice for it to countdown as they type. 

It would be nice if the help text would do this automatically, but I'm willing to remove the help text and add some html below the box if someone has done this. 

Thanks in advance!
