from the events, it is on action button, if this is the start where it shows this dialog,
you need to turn it into a autorun, if its the action button, page 3 is ALWAYS run,
while the condition of page 1 and 2 are met, while you have a condtion:
if: Pary meet IRA leader, (asuming this is a switch), the condition is met,
you can put a selfswitch on the bottom on those pages.
(at the bottom), selfswitch A = ON)
condtion: selfswitch A = ON
at the bottom, selfswitch B = ON
condition: selfswitch B = ON,
at teh bottom, selfswitch C = ON
condition: selfswitch C = ON
maybe a text here as well so you cant interact further with it.
All 3 Eventpages have no conditions, that means their condition is fullfilled.
Only the highest Eventpage that is fullfilling its conditions will be Active.
That means in your Setup Eventpage 3 is always Active and Page 1 and 2 will never be.
Edit3: And on Page 3 The conversation doesnt run, because you dont have the Item for which the condition is checking. Because Page 2 never run and therfor you never obtained the Item.
Honestly, you could probably merge it all into one page since they're all confined by a conditional branch. Unless you're able to have more than one of those items in your inventory at a time. If that's the case, put the item requirement on each page in the dropdown box labeled 'Item'.
