Twine: 2.1.1
Harlow: 2.0

Ok so, I've been working with Harlow on and off today and I've come to something that has me stumped. In a normal programming language it would be simple, but I'm not sure how to proceed with Harlow.

So the idea that I want to run with is to have long passages slowly build themselves as the user makes choices. Basically, scenes evolve as a whole rather than one passage to the next.

For instance:

Name?

(Choices
Dennis
Hailey)

(User chooses Dennis and both choices vanish and a new block of text appears:)

Nice to meet you Dennis, how old are you?

(Choices
18
25)

Etc.

This is something I used to do in Quest Text, but everyone told me to move to Twine so that's what got me here.

So I've figured out that I need to use Hooks, so I've got:

"Name?"

["Jesse Jackson"]<nameDisplay|
["Taylor Swift"]<nameDisplay|

(click: ?nameDisplay)[(if: ?nameDisplay is "Jesse Jackson")[Right] (else:)[Wrong] ]

I attempted to convert the ?nameDisplay to a variable ($nameDisplay) but I think I'm missing something?
