How can I save a entity for another code?

[AwesomeGunGuy]

Hello all,
I am trying to let the player execute a command after he interacted with an entity before something will happen to that entity. How can I do this?
Here is an simple example

on right click on pig:
    set {askquestion.%player%} to 1
    send "want to change the name?" to player
    send "/yes or /no" to player

command /yes:
    trigger:
        if {askquestion.%player%} is 1:
            set entity's display name to "example"
            set {askquestion.%player%} to 0
            send "name changed!" to player
command /no:
    trigger:
        if {askquestion.%player%} is 1:
            set {askquestion.%player%} to 0
            send "name unchanged" to player

This example wont work, but how can I make it work?
Thanks in advance!

You can store entities in variables, it just doesn't persist over server restarts. Set the player's variable to the entity itself then you should be able to see its name by referencing the variable.

Also, you should be deleting the askquestion variable instead of setting it to 0. It's better to remove variables once they're not being used instead of setting them to some sort of pseudo-empty value since they're just taking up unnecessary space in your variable storage, which affects load times (minorly, but it will add up if you do stuff like this often).
