Google Sheets: Forms edit with multiple questions fix duplicate answers - google-sheets

Question

I have a form that has a Question that depending upon an answer will direct you to futher questions. The problem is, once you submit the form and then go back and edit your answer, if you choose another answer for the first question and it redirects to a new question because your first answer was different, the response in Google Sheets keeps both answers. How can I fix this so that it only shows the last answers? For example. When I first answer the question, I choose Option 1.
Then when I choose next I get these options.
Which once I submit will give the following response submission in Sheets.
Ok, so then if I go back and Edit my response like so...
It will redirect to a different question based on my first choice.
However, once I submit my final answer, this is what the subission looks like in Sheets.
The problem is, Column C and D answers are no longer relevant based upon the answer in Column B. How can I fix this so that Column C and D are blank as they should be and I only get the answer that is correct based upon the submission in Forms?
Thanks!

Answer 1

You can create a bound script in your Google Sheets with a Form Submit trigger.
Sample Code:
function formSubmission(e) {
Logger.log(JSON.stringify(e));
Logger.log(e.values);
var data = e.values;
var row = e.range.rowStart;
var sheet = SpreadsheetApp.getActive().getSheetByName('Form Responses 1');
if(data[1]=="Option 1"){
//Remove data under Follow-up Question2 and Amount 2 (Column E and F)
sheet.getRange(row,5,1,2).clearContent();
}else if(data[1]=="Option 2"){
//Remove data under Follow-up Question1 and Amount 1 (Column C and D)
sheet.getRange(row,3,1,2).clearContent();
}
}
Pre-requisite:
What it does?
Get the form submitted values using Sheets form submit event object values
Get the form submitted target row using range.rowStart
Get the active spreadsheet and sheet with the name Form Responses 1
Check the Option selected and delete specific columns depending on the option selected.

Here's how I finally was able to do what I needed Ron M's help:
function formSubmission(e) {
Logger.log(JSON.stringify(e));
Logger.log(e.values);
var data = e.values;
var row = e.range.rowStart;
var sheet = SpreadsheetApp.getActive().getSheetByName('Form Responses 1');
if(data[4]=="Debit"){
sheet.getRange(row,7,1,1).clearContent();
}else if(data[4]=="Credit"){
sheet.getRange(row,6,1,1).clearContent();
}
if(data[7]=="INCOME"){
sheet.getRange(row,10,1,14).clearContent();
}else if(data[7]=="HOME"){
sheet.getRange(row,9,1,1).clearContent();
sheet.getRange(row,11,1,13).clearContent();
}else if(data[7]=="LIVING"){
sheet.getRange(row,9,1,2).clearContent();
sheet.getRange(row,12,1,12).clearContent();
