Adding points to a score when timeline ends?

Hello,

I'm building a game in Storyline using custom graphics, everything is going well except for adding points to a slide without any interaction from the user. Would anyone know of the best way to do this?

Currently all slides are 'pick one' slides with a results slide.

What I would like to happen:

After 11 seconds on slide, 10 points are automatically added to score and slide advances.

My imperfect logic on how it should work:

1. After 11 seconds, add 10 points to score.
2. Then advance to next slide or programmed slide.

Your awesome solution

Thanks
