how do I make it so that when a person types in

as

ask [] and wait

it says whatever the person said in a random order

like if the person said hello it would show like elolh or something

Add each letter of answer to a list and then pull out a random letter from the list deleting as you go and joining each letter to the output.

set [output  v] to []
repeat until <(length of [letter list v]) = [0]>
set [index v] to (pick random (1) to (length of [letter list v]))   
set [output v] to (join (output) (item (index) of [letter list  v]))
delete (index) of [letter list  v]
end
