How do I set Instance variable as random(10, 30)?

Sprite On Created: Sprite set var to random(10,30)

Note, if you want an integer number from 10 to 30, the correct expression is int(random(10,31))

On start of layout

For each sprite -> set instance variable

"On created" will still be triggered for them.
