Dialog help

I've looked up for many dialog tutorials that would give me further Help with dialogs.
The ones i saw gave me beginner and easy dialogs.
I want to make some chained dialogs for many players example:

Unit click a dialog button
-Another diablog folows
Unit presses a dialog buttong (out of 4 buttons) and a unit is spawned
(human,orc,undead,elf)

How do i do such complicated dialog (for me)

Gosh that was an idiot post i found out how myself...
