Display the Answer to a Previous Q in gApps Forms - google-apps-script

Question

I would like a question in my form to display the answer to a previous question. I am not asking about question logic or the Go To feature.
For example:
Q1: What type of entree would you like?
Meat
Fish
Vegetarian
Q2: Which cuisine do you prefer?
Indian
American
Mexican
Page break.
Q3: In the previous questions, you selected an [Q2] [Q1] entree.
If the answer to Q1 was Meat and to Q2 was Indian, then Q3 should display:
In the previous questions, you selected an Indian Meat entree.
This is possible in SurveyMonkey (with the use of square brackets). Can this be done in Google Forms?

Answer 1

I've written some dirty code in the boss´ time
It's a mix of server and client side script, I could have created the question Q3 in the function q1H & q2H.
var q1A = new Array(" Meat", " Fish", " Vegetarian")
var q2A = new Array(" Indian" ," American", " Mexican")
function doGet(e) {
var app = UiApp.createApplication().setTitle("Dev Test Sitemap");
var mainPanel = app.createVerticalPanel()
var homePanel = app.createHorizontalPanel()
var q1 = app.createLabel("Q1 What type of entree would you like?")
var q1ListBox = app.createListBox().setName("q1ListBox") ;
for (var i = 0; i < q1A.length; i++) {
q1ListBox.addItem(q1A[i]);
}
var handlerQ1 = app.createServerHandler("q1H");
q1ListBox.addChangeHandler(handlerQ1)
mainPanel.add(q1);
mainPanel.add(q1ListBox);
var q2 = app.createLabel("Q2 Indian American Mexican?")
var q2ListBox = app.createListBox().setName("q2ListBox") ;
for (var i = 0; i < q2A.length; i++) {
q2ListBox.addItem(q2A[i]);
}
var handlerQ2 = app.createServerHandler("q2H");
q2ListBox.addChangeHandler(handlerQ2)
mainPanel.add(q2);
mainPanel.add(q2ListBox);
mainPanel.add(app.createLabel("----------------------------------- pagebreak ---------------------") );
var horP = app.createHorizontalPanel()
//Q3: In the previous questions, you selected an [Q2] [Q1] entree.
var q3 = app.createLabel("In the previous questions, you selected an")
horP.add(q3)
var q2ans =new Array()
for (var i = 0; i < q2A.length; i++) {
q2ans[i] = app.createLabel(q2A[i]).setId("q2A"+[i]).setVisible(false);
horP.add(q2ans[i])
}
var q1ans =new Array() ;
for (var i = 0; i < q1A.length; i++) {
q1ans[i] = app.createLabel(q1A[i]).setId("q1A"+[i]).setVisible(false);
horP.add(q1ans[i])
}
var q32 = app.createLabel(" entree")
horP.add(q32)
mainPanel.add(horP);
app.add(mainPanel); //red
return app.close();
}
function q1H(e) {
var app = UiApp.getActiveApplication();
var q1ListBox = e.parameter.q1ListBox;
for (var i = 0; i < q1A.length; i++) {
if (q1ListBox == q1A[i] ){
app.getElementById("q1A"+[i]).setVisible(true);
}
}
return app;
}
function q2H(e) {
var app = UiApp.getActiveApplication();
var q2ListBox = e.parameter.q2ListBox;
for (var i = 0; i < q2A.length; i++) {
if (q2ListBox == q2A[i] ){
app.getElementById("q2A"+[i]).setVisible(true);
}
}
return app;
}
