Pick the correct two out of three

Hi all

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
