In the change attribute behaviour you can go in the expression editor (by clicking the small "e") and if you drop down the menu you can select "Rand" (= Random)
Your behviour should look like this: change attribute = rand(minimum, maximum)
Substitute minimum with the smallest number eligible and maximum with the maximum number. example= rand(0,10) This will prodice a number from 0-10 randomly.
