make quest rpgxp

i'v made my game but i want to make a quest to make it more chalenging can someone plz make a picture aided tutorial on how to make a quest

simple quest, zombie wants some parts collected you either get him back to the grave or take the quest, zombie is happy when you give him all of the pieces and he give you an award and then it shows how much i was noobish when i made it

hmm instead of the zombie running off silliness, it's better to turn on a switch then make a new page and condition it with the switch.
that page is empty.
or you can leave it as is and then when the player tries to talk to the zombie he will get a message and the zombie will flee.. sorta...
