How long does an object persist, i.e. if I create an object on one screen, can I refer to it on another screen?

For example, I retrieve data from a database and store it in an object on one screen. I can of course save the data from the object to variables or to local storage, to allow it to be used on any screen, but can I cut out this step and refer to the object on another screen?

What do you mean by an object? Using the `create object` block? Can you give an example? Any value you want to re-use needs to be stored in a variable, local database or cloud database.

Yes - the create object block. If I create it on one screen, can I refer to elements of that object block on another screen.

Assume that I have connected to a database, retrieved the record\_id from the database which is stored in the object.  
If this is used on one screen, can I refer to the object element fromDB.record\_id on another screen using a get property block?

Yes, as long as you are getting/setting the object properties using **variable** (and object) blocks. In your screenshot, your object “lives” in `app variable fromDB`. So that’s the variable you can use. The object doesn’t exist outside of that variable.
