Hi Zoë,
You code indeed shows the feedback text for me, but the code I gave also does so. Did you make sure to update to PennController 1.8? There was a bug with testing non-waitedKey elements in prior versions.
And as you said, all of this is just to make sure you see the feedback text, but the code in this message still increments the Var element as expected (with 1.8 at least)
