Feedback to mouse answers

Hi!
I started with psychopy just recentely, and I don’t understand about coding.
I’m creating a perceptual auditive test, this video shows how far I could get.
I’m trying now to make the feedback for Practice Test – Part 1, but I’m lost.
The conditions file looks like this:

And in the builder is like this:

I tried to follow your instructions for making a feedback, also saw the stroopExtended of the Demos, but nothing.
My participants are answering with mouse not keyboard, so this is a big difference, I can’t find in the mouse definitions ‘store correct’ as for keyboard.
Could someone help me?
Thank you in advance,
Gabriela
