Text box prompt

Hi guys,

writing a story on Harlowe, and am stuck again here. First let me explain the scene.

Passage 1:

David learns the gang that killed his father were the Blue Jackets

Passage 10:

David meets with a police officer who might be able to share the information. He asks David "Do you remember the gang name?"

[[Yes i do]]

[[No i don't]]

by clicking Yes i do, it takes the player to passage 11 which immediate displays a prompt text box (what is the gang name?"

if player answers blue jacket, he sees this passage "yeah i know them... Let me pull out a file on their leader"

If the player answers any thing else he sees "Nah, haven't heard of them.. i got nothing on file"

So ive got the text box to prompt the gang name, how do i link it the results typed in the the correct passage?

Thanks guys
