JesseJames11 - What are you trying to accomplish? If you are trying to save a game state and later loaded by the player then you can use the system action (Save)
System --> Save --> Slot("Save Name")
If you are trying to save values like coins then you can use the localstorage. Arrays works like variables but comes with three values per row (X, Y, Z) unlike variables which only has X per variable, and arrays are not saved on close of app. But array values can be downloaded to the LocalStorage so that it can be saved even when app is closed and loaded afterwards whenever you want to, like "on game start up" or "start of layout".
In conclusion,
If you want to save game state:
System --> Save --> Slot("Save Name")
If you want to save game values:
Storage:-------Persist on close of app:---Can be set on LocalStorage:
