Showing a layer depending on question outcome?

Hi all

I have a knowledge check where I've got a custom 'Continue' button rather than using the Player's submit. At the end the learner can 'Review' all questions and change answers if they want. I then have a 'Submit' button that submits all to the results slide; all good.

I have a 'Review' button on the Results slide and currently have the default 'correct/incorrect' trigger switched on.

What i want is to show a custom 'correct/incorrect' layer show when the learner clicks 'Review' from the Results slide. What built-in variable can i use that relates to the outcome of each question slide?

I can then add a trigger to each slide stating something like 'Show later xx if variable xx is correct' - and the same for incorrect.

I just don't wanna use the built in 'correct/incorrect' as it looks ugly to me! Sorry Articulate ;) - editable feedback would be great by the way!!
