I want to create a prompt walk through of entering text into specific columns of google sheet (i.e. a set of Mandatory fields)

Firstly I'm very inexperienced in coding, so my attempt so far has is based on my research online. I'm sure I have over complicated the script by repeating elements of the script.

I want it to be able to do the following

1 - Click on custom menu. 2 - Click on Add new Risk. 3 - Prompt box asks 4 sequence of questions - (As an example Name, Age, Address & Job). 4 - The responses are captured and put into the next available row in the sheet. 5 - The prompt box cancels the whole process by clicking the cross or the cancel button.

Problems to overcome

1 - So far I can get the script to ask the sequence of questions however it only pastes the last question response the next available row.

2 - I cant work out how to cancel the process, it just brings up a message and carries on the sequence of commands

3 - I need my responses to be fixed to specific columns i.e - Not all pasted into A2,B2,C2,D2. For example Name(A2), Age (G2), Address (H2) , Job (X2)

Any help would be much appreciated

      .createMenu('Risk Menu')

  var ui = SpreadsheetApp.getUi(); // Same variations.

A Custom Prompt Form with text input and a select

You can use this as a dialog or a webapp as the doGet() is included. Theres just a couple of minor mods to run as a webapp. One is identified in the script.html file with comments for webapp and/or dialog and the other is just to change the name of the Cancel button to Cancel/Reload. And that's it.

Code.gs:

function onOpen(){
  SpreadsheetApp.getUi().createMenu('My Menu')
  .addItem("Show Dialog", 'showMyDialog')
  .addToUi()
}

function saveData(dObj) {
  var ss=SpreadsheetApp.getActive();
  var sh=ss.getSheetByName('Sheet1');
  var rg=sh.getRange(1,1,1,sh.getLastColumn());
  var hA=rg.getValues()[0];
  var vA=[];
  for(var i=0;i<hA.length;i++) {
    vA.push((dObj[hA[i]])?dObj[hA[i]]:'');//Column headers must agree with form names
  }
  sh.appendRow(vA);
  return;
}

function showMyDialog(){
  var ui=HtmlService.createTemplateFromFile('TheHtml').evaluate();
  SpreadsheetApp.getUi().showModelessDialog(ui, 'Form Data');
}

function doGet(e){
  return HtmlService.createTemplateFromFile('TheHtml').evaluate();
}

function include(filename){
  return HtmlService.createHtmlOutputFromFile(filename).getContent();
}

function getSelectOptions() {
  var ss=SpreadsheetApp.getActive();
  var sh=ss.getSheetByName('Options');
  var rg=sh.getDataRange();
  var vA=rg.getValues();
  return vA;
}
