Here’s an example of how to do it:
*choice choicename1 choicename2
–#choice1 option1
----#choice2 option1
------You selected the first option of both the first choice and the second choice.
----#choice2 option2
------You selected the first option, then the second option.
–#choice1 option2
----#choice2 option1
------You selected the second option, then the first option.
----#choice2 option2
------You selected the second option of both the first choice and the second choice.
You can stack as many choices as you want on the same page. Also, make certain that your second (and deeper) choice options are all named the same. The extra names on the *choice line are not optional either. It will say “Select a(n) [choicename]” with a(n) decided on by the first letter of the ‘choicename’. ‘choicename’ can also be one word, and no kind of {variable} or anything else I could figure out seemed to effect it.
I hope that’s clear and helpful. If not you can take a look at how I actually coded it here (Starts on line 12):
