Hi Carla,
so far, so good.
There are no pictures in the tutorial yet, so it's not that easy to
follow.
An audio-interface is the same as a soundcard, it's just a different
name. Your 'soundcard', for example, isn't a card, so some people like
to use audio-interface instead.
So you need to choose the interface the jack server should use.
Try to click on the little > besides the interface option, try to
identify your onboard soundcard and select it. If you can't identify
it, try (default).

Then try what the tutorial suggests: tick the realtime checkbox, set
the Frames/Period to 1024 and the Periods/Buffer to 3.

Click the OK-button to close the setup dialogue, press the Start button
and see if the jack-server starts.

If it does, good. If not, there's something wrong.
When it is running, look at the display. If there's a red number that's
increasing, you need to tune your settings, else you'll experience
dropouts.
Be aware that it's rather hard to get good performance out of jack with
onboard audio interfaces.

Regards,
