I'm still missing something @ashley. I put the (4) text choices in a family and added the family to your expression. I hoped it would choose a random family member like it does when you use family in create. Unfortunately, nope - it just kept using the first text in the family.
I guess I don't understand your suggestion,
put the expression in a "pick random" event
The endgame is a random answer generator that uses the typewriter effect
I've included the C2 file if my description isn't clear.http://www.danielwheeler.net/SB/random_text.zip
