I forgot to say, its not about taking a decision, its a sequence.
I have 4 buttons that change the text and the next step
I created variables and what happen with the buttons according to a variable
Eg. variable potato = 1 the button 1 "potato" > person clicks it, gets a pic of a potato, set the variable "fish" to 1
variable fish = 1 so button 1 now is named fishes and show a pic of fishes instead of the potato when clicked
Does it make sense?
