1. It's the formatter, really :)

2. Okay, cool.

3. How do you define onSuccess? I've tried the following with the
non-existing 'bag', but don't see the error in the Firefox's JavaScript
console, which prompts me to think that its not being called. Am I using a
wrong protocol for this? The request itself works just fine.

(html request)
  triggerForm: fid;
  onSuccess: 'bah()';

Yeah, interesting process. I experienced similar trial-and-error exercises

1. Your brackets and semicolons are very strangely placed. I think
they are probably wrong and cause some problems.

2. You don't need "html evaluator" if you don't inject a script into
the web-page, just use "html request" for simple requests.

3. The AJAX objects (request, updater, evaluator, etc.) understand a
set of events, such as #onComplete:, #onFailure:, #onSuccess:, etc. I
would use one of these events (probably #onSuccess:) to change the
class of your element. Maybe write a helper function in JavaScript
that takes the element and the checkbox as parameters and toggles the
classes appropriately. Then you can attach this function to the event

Hope this helps,
