Google Script - Attachments to Drive - file-upload

Question

I have the code below, but i've been struggling to get it to work properly, either it creates duplicate folders every time i run it, or it doesn't upload the attachments and just creates the folders... I am also getting an error now that the newMail Uploads object does not have a .hasnext() function.
What i want to do, is have this script running and it puts attachments in a folder relating to their label -- So in the code below, all mail with the newMail label would go to a single folder, but i want to be able to extend the code further to run for multiple labels ect, so i want to check if the relevant folders exist and if not create them, if they exist they should be used.
-Edit, Now it is only taking the attachment from the first email from a certain address.
function startProcess()
{
var gmailLabels = "newLabel";
var driveFolder = "newFolder";
var archiveLabel = "Processed";
var moveToLabel = GmailApp.getUserLabelByName(archiveLabel);
if ( ! moveToLabel )
{
moveToLabel = GmailApp.createLabel(archiveLabel);
}
findFolder(gmailLabels, driveFolder, archiveLabel, moveToLabel);
}
function findFolder(gmailLabels, driveFolder, archiveLabel, moveToLabel)
{
var filter = "has:attachment label:" + gmailLabels;
var folder = DriveApp.getFoldersByName(driveFolder);
if (folder.hasNext()) {
folder = folder.next();
} else {
folder = DriveApp.createFolder(driveFolder);
}
callThreads(gmailLabels, driveFolder, archiveLabel, moveToLabel, filter, folder)
}
function callThreads(gmailLabels, driveFolder, archiveLabel, moveToLabel, filter, folder)
{
var threads = GmailApp.search(filter);
for (var x=0; x<threads.length; x++) {
var label = GmailApp.getUserLabelByName(gmailLabels);
var message = threads[x].getMessages()[x];
var desc = message.getSubject() + " #" + message.getId();
var att = message.getAttachments();
for (var z=0; z<att.length; z++) {
try {
file = folder.createFile(att[z]);
file.setDescription(desc);
}
catch (e) {
Logger.log(e.toString());
}
}
//threads[x].addLabel(moveToLabel);
label.removeFromThreads(threads);
//threads[x].moveToTrash();
}
}

This is just a suggestion. I haven't tested this code, it probably doesn't work. But that's not the point. I'm trying to show how you might create some order to your code so that it's easier to understand and debug:
function sendToGoogleDrive() {
makeNewFolders();
putEmailsIntoFolders();
};
function makeNewFolders() {
var gmailLabels = "newMail";
var driveFolder = "newMail";
var archiveLabel = "Processed";
var rootUploadFolders ="newMail Uploads";
var rootDriveFolder = DriveApp.getFolders();
var rootExist = false;
var childExist = false;
while (rootDriveFolder.hasNext()) {
var folder = rootDriveFolder.next();
if(folder.getName()==rootUploadFolders) {
var folderId = folder.getId();
if(folder.getName()!==driveFolder) {
var child = DriveApp.getFolderById(folderId).createFolder(driveFolder);
};
};
};
};
function putEmailsIntoFolders() {
};
