How can I script a Google Form from a Spreadsheet to go to a specific page based on an answer?

Question

I have successfully created a Google form that populates from a spreadsheet using code adapted from here: https://www.youtube.com/watch?v=BYA4URuWw0s . Now I would like to make the form go to a specific question based on the answer of a previous question without losing the function of updating from the spreadsheet. I have tried to alter code from here: How to assign Go_To_Page in Form Service on Multiple Choice? , but have yet to have any luck. Below is what I have as of now. I am very new to coding and any help will be greatly appreciated. Thanks in advance!!!

Answer 1

PageBreakItem

A layout item that marks the start of a page. Items can be accessed or created from a Form.

PageNavigationType

An enum representing the supported types of page navigation. Page navigation types can be accessed from FormApp.PageNavigationType.

The page navigation occurs after the respondent completes a page that contains the option, and only if the respondent chose that option. If the respondent chose multiple options with page-navigation instructions on the same page, only the last navigation option has any effect. Page navigation also has no effect on the last page of a form.

Choices that use page navigation cannot be combined in the same item with choices that do not use page navigation.

// Create a form and add a new multiple-choice item and a page-break item.
var form = FormApp.create('Form Name');
var item = form.addMultipleChoiceItem();
var pageBreak = form.addPageBreakItem();

// Set some choices with go-to-page logic.
var rightChoice = item.createChoice('Vanilla', FormApp.PageNavigationType.SUBMIT);
var wrongChoice = item.createChoice('Chocolate', FormApp.PageNavigationType.RESTART);

// For GO_TO_PAGE, just pass in the page break item. For CONTINUE (normally the default), pass in
// CONTINUE explicitly because page navigation cannot be mixed with non-navigation choices.
var iffyChoice = item.createChoice('Peanut', pageBreak);
var otherChoice = item.createChoice('Strawberry', FormApp.PageNavigationType.CONTINUE);
item.setChoices([rightChoice, wrongChoice, iffyChoice, otherChoice]);

You can follow the sample create by Google and the implementation used in Mogsdad's answert to further understand the flow.

I've added his code snippet:

function createForm() {
// Create a form and add a new multiple-choice item and a page-break item.
var form = FormApp.create('Form Name');
var item = form.addMultipleChoiceItem();
item.setTitle('Do you like Food')
var page2 = form.addPageBreakItem()
.setTitle('Page 2')
var item2 = form.addTextItem();
item2.setTitle('Why do you like food?')
var page3 = form.addPageBreakItem()
.setTitle('Page 3')
var item3 = form.addTextItem();
item3.setTitle("Why don't you like food?") 

item.setTitle('Question')
.setChoices([
item.createChoice('Yes',page2),
item.createChoice('No',page3)
]);
}
