Pick the correct two out of three
I'm trying to set up a quiz so that learners must choose the correct two options out of a possible three. I want them to see different feedback depending on what they choose:
* a hint if they choose only one of the correct options
* 'well done' if they choose both
* 'try again' if they get neither.
I thought the logic I used in the attached file would allow me to do this, but it's not working and I can't see why.
Can anyone help me understand why the attached doesn't work and what I need to do to fix it?
Thanks so much
