Sorry I didn’t see this earlier! yes, there is a way to get the results of the action. In the case above, it’s the message String that’s returned.
Using merge syntax, you can do this: {{$PreviousAction.result.message}}
Using JS, if you add a snippet after your action, you should be able to see the same PreviousAction via this:
var params = arguments[0],
$ = skuid.$;
console.log(params.$PreviousAction.result.message);
