Yes, breaking up your chains is one of the first things do do when you're
having trouble. For example:

    var $test = $('#test :textarea');
    $test.before('Current length:&nbsp;<span id="'+ this.id
        +'_len">'+this.value.length+'</span>&nbsp;characters');
    $test.keypress( function() { 
         var $len = $('#'+this.id + '_len');
         $len.css('color', ((this.value.length >
parseInt(this.id.split()[1]))?'red':'green'));
         $len.html(this.value.length);
     });

Now you'll find it easier to debug.
