Form Responses Creating New Google Sheets Tabs Rather then Bucketing - google-apps-script

Question

I have a Google Sheet which is storing the answers to my form and in theory should bucket the responses by the value selected from a drop down for my form labeled "Location of Change". So far the script accurately creates a new sheet from each response and adds a row with that responses information to newly created sheet, but it creates a new sheet for every response rather then add add responses that contain the same value selected from "Location of Change" to the same sheet.
I assume this is happening because there is a disconnect between the destSheet variable that looks for the values of the "Location of Change" and the getSheet() function, but I could be wrong.
Here is my code:
function onSubmit(e) {
//Open Marketing - Discoveries and Changes - v1
var sheet = e.range.getSheet();
//Return Spreadsheet that contains this sheet
var ss = sheet.getParent();
//Open Marketing - Discoveries and Changes - v1
var form = FormApp.openByUrl(ss.getFormUrl());
//Destination sheet based on "Location of Change"
var destSheet = getSheet(ss, e.namedValues["Location of Change"]);
//Store response in destination sheet
destSheet.appendRow(e.values);
function getSheet( spreadsheet, sheetName, headings) {
spreadsheet = SpreadsheetApp.getActive();
var sheet = spreadsheet.getSheetByName(sheetName);
if (sheet == null) {
sheet = spreadsheet.insertSheet(sheetName);
if (headings && headings.constructor === Array) {
sheet.getRange(1,1,1, headings.length).setValues([headings]);
}
}
return sheet;
}
}

Answer 1

I think the problem is that e.namedValues stores all values as arrays even if there is only one value. So e.namedValues["Location of Change"] should be
e.namedValues["Location of Change"][0]
