Batch sequence from 2 folders

Question

Hello,
I would like to create a code, where I have a sequence of files in a Left folder and a sequence of files in a Right folder. The goal is to open the left image (L_001) and place the right image (R_001) on top, by creating a new layer. Bottom layer to be called, 'Left' and top layer to be called, 'Right'. Then save the two layered image as a PSD. Then to carry on, L & R _002, 003, so on.
Can you advise me on a code to perform this?
Thanks!

// dialog for folder-selection;
var theFolderOne = Folder.selectDialog ("Choose the correct LEFT folder of images");
var theFolderTwo = Folder.selectDialog ("Choose the correct RIGHT folder of images");
var theFolderThree = Folder.selectDialog ("Choose the correct MERGE folder of images");
if (theFolderOne && theFolderTwo && theFolderThree) {
var theFilesOne = theFolderOne.getFiles(checkFor);
var theFilesTwo = theFolderTwo.getFiles(checkFor);
// check if both folders contain the same number of files;
if (theFilesOne.length != theFilesTwo.length) {
alert ("the folders don’t contain the same number of images")
// else do the stuff;
else {
// create the psd-options;
psdOpts = new PhotoshopSaveOptions();
psdOpts.embedColorProfile = true;
psdOpts.alphaChannels = false;
psdOpts.layers = true;
psdOpts.spotColors = true;
// run through the files;
for (var a  = 0; a < theFilesOne.length; a++) {
// open background-image;
var theFile = app.open(File(theFilesOne[a]));
theFile.activeLayer = theFile.layers[0];
// place foreground-image;

// save the combined files;
theFile.saveAs(new File (theFolderThree + "/LRMerge" + bufferNumberWithZeros((a + 1), 3) ), psdOpts)
theFile.close(SaveOptions.DONOTSAVECHANGES)
////// check for psd, tif or jpg //////
function checkFor (theFile) {
if (theFile.name.slice(-4) == ".psd" || theFile.name.slice(-4) == ".tif" || theFile.name.slice(-4) == ".jpg") {return true}
else {return false}
////// buffer number with zeros //////
function bufferNumberWithZeros (number, places) {
var theNumberString = String(number);
for (var o = 0; o < (places - String(number).length); o++) {
theNumberString = String("0" + theNumberString)
return theNumberString
I have adjusted this code in terms of folder name in the first few folders, but what I would like to do now is select the background layer and rename that to 'Left' and then the layer on top 'R_xxx' to 'Right'. Not so great at coding, but would appreciate if someone could implement the request into the code above please?
