Use recursion:

Code:

factorial: t1
t1 = 0 ifTrue: [^ 1].
^ t1 * (self factorial: (t1-1))

Thank you guys so much! big_smile

But I have one more question: Whenever I make a reporter or boolean, the little checkmark that can show or hide a variable appears. The display is glitchy--when you update the number, instead of updating, it shows a new one. How do you turn off the ability to show/hide the value?

Scratch has a method for that.

You're smart enough to know how to edit that smile
