Help needed Partial feedback logic in Storyline 360 multi-select quiz

Hi everyone,

I’m stuck with a custom multi-select question in Storyline 360 and can’t get the Partial feedback to behave correctly.

My setup:

• 4 answer buttons (using button states only, no variables)
  • A, B, D = correct
  • C = incorrect
• Learners select their answers, then click one of three confidence buttons:
  • Very Confident
  • Confident
  • Not Sure
• Based on the answers + confidence, a feedback layer should appear
  (e.g. Correct / Very Confident, Partial / Confident, etc.)

What works:

• Correct feedback works perfectly
  • A + B + D selected
  • C not selected
• Incorrect feedback works
  • C selected
  • A, B, D not selected

The problem:
As soon as I add a Partial feedback trigger, it always fires — even when the learner selects the fully correct answer.

For example, my Partial logic is something like:

• Show Partial layer if A OR B OR D is selected

That works for partial answers, but it’s also true when A + B + D are all selected, so Storyline ends up showing the Partial layer on top of the Correct layer.

If I remove the Partial trigger, everything else works as expected.

What I’ve tried:

• Changing trigger order
• Tightening the Partial conditions
• Trying to exclude the Correct case using state checks
• Looking for a way to group conditions with AND (doesn’t seem possible)

My question:
What’s the best practice in Storyline for handling Partial feedback on a multi-select question when using states only?

• Is it possible to stop Partial from firing when Correct is true?
• Should Partial be handled using an ELSE instead of a separate trigger?
• Or is this a limitation that really requires variables?

Any advice or examples would be really appreciated.
Thanks!
