B2010 - How do I make a multiple choice question when the user must click two responses? by - Joseph Ganci This example shows you how to set up a multiple choice question
in which the user must click two answers to be correct. While
there are more elegant solutions, this is one of the easiest to set up and explain.
The first
Calculation icon, reset choices, contains a short script: choices := [FALSE, FALSE, FALSE, FALSE] This sets up a linear list called choices with four locations,
each set to the value FALSE. The Interaction icon contains four objects
to be clicked on the screen. Each of the four Calculation icons attached,
numbered 1 through 4, contains a script line. The first one contains the
line choices[1] := TRUE All the others contains the same code, except that the number within
the square brackets, which is the location in the choices list, changes
to the name of the icon. Note that each of the four Calculation icons, which act as feedbacks
when the user clicks the hot spots, are set to Continue branching. The Map icon
at the end is set to activate its feedback on the condition that the Authorware
variable ChoicesMatched , which indicates how many of the choices the
user has clicked, becomes The Calculation icon contains the following script: -- in this case, we assume that the correct answers are
2 and 4 The script checks the value of choices[2] and choices[4],
the correct answers in this case. If both are TRUE, then the result of the &
operation is TRUE, and the variable called path is set to 3.
If they both aren't true, then path is set to 2 only if one or
the other of choices[2] and choices[4] is TRUE. If neither one is TRUE,
then path is set to 1. The Decision icon is set to Calculated Path branching and
the branch expression is simply path, meaning it will take the first
path (both wrong) if path is 1, it will take the second path
(one right, one wrong) if path is 2, and it will take the
third path (both right) if path is 3. Each of the Display
icons contains a message posted to the screen appropriate to the Display icon's
title. This example

I am having trouble finding an example of a quiz interaction for a question wherein the user would pick two choices to get the correct answer. One possible answer
would be 1 right / 1 wrong, another would be 2 wrong, and the third
would be 2 right. Any examples or suggestions on where to look would be appreciated.
2. The Map icon contains the following: 
if choices[2] & choices[4] then path := 3
else if choices[2] | choices[4] then path := 2
else path := 1
2.
The Map icon contains the following:
if choices[2] & choices[4] then path := 3
else if choices[2] | choices[4] then path := 2
else path := 1
