How do i build conditional logic digital assistant

Again .. this is probably really basic, but I could not find a tutorial how to do this ..

So I want to build a FAQ but the answer depends on some additional info you want to subtract from the user.

Like i said, this is probably really basic, but it's not in the general Foodskill lab and I'm running into several things I can't easily figure out.

In my example I want to ask first whether the user knows whether a contract exists before the user wants to create an order. I've created an entity contractExists with values Yes, No, Don't know. But not used it so fwar.
