Ren'Py : A choice in a choice ? [Sloved(In some way)]

[KuroPan]

Hello (again and again) !
I've got question:
Is it possible to put a choice in a choice ?
I mean something that will looks like :

---------------

Amy(your pretty assistant) : Who do you want to see first, Sir ?

[choice time !]

- The Old man
- The little child
- the policeman
- No one.

[You choose the policeman (for example).]
[ You talk with him]

Policeman: When I arrived, the victim was already dead.
You : Ok, then ?
Amy : You should ask him specific questions.
You : (Huh, she's right !)

[Choice Time !]

- Ask about the time of the crime
- Ask about the victim
- Ask about somethin else

---------------

Then, you've made all the possibilities for the policeman.
And you want to return at the first menu, when Amy asks who would you want to see.
Is it possible to do this ?
If : yes, it is
So : how can, we do that ?

END

Thanks to you ?

Use conditionals:
https://www.renpy.org/doc/html/conditional.html
You need something to check if the choice has been made, and set the choice as made when it is selected.

If the documentation is too confusing (shouldn't be, its some of the most basic parts of Ren'Py you really should learn) then it can be arranged to give an example.
I'd give you an example now, except I gotta go to work in a few hours: https://puu.sh/vSQJe/1536602013.png

I have a good level in English, but it's difficult to understand sometimes. Especially if there are plenty of codes.
Especially for french people.
It takes me a long time to actually understand.
That's not an excuse.
Thanks for the help !
