Queries custom page

Hi,
I need your help.

I want to create a custom page where the user must answer a question if a plugin is installed.

If he clicks yes an other custom page "password" should be shown. If he clicks no the other custom page should be skip.

Can you say me how I can do this?

Would be very friendly 🙂

Here is a screen from the "question" custom page:

On the 2nd custom page create function, read the state of 1st page radio buttons.
If radio button "no" is 1 (checked) then skip the page.
e.g.
ReadINIstr $1 "ini_path\ini_name" "field_num" "state"
${if} $1 == 1
Abort
${endif}
