Font Text

[admin]

Here's a working example:

Code:

$(function() {
  if (window.grp) {  
    grp.listen('32/1/2', function(object, state) {
      var size = Math.max(12, object.value);
      $('.size').css('font-size', size + 'px');
    });
  }
});

32/1/2 is the groups address that sets the size. size is the Additional class of the element where font size should be changed dynamically.
