Extend Google Apps Script

I have an HTML form that inserts data in a Google Sheet using Google Scripts. Your job is to expand the script by allowing: Multiple File Upload: I already have the script create a folder based on the client name and place the one file into the folder and then link the file directly. Your job is to allow the form to accept multiple files and instead of linking to the file directly, you must link to the folder that is created to the N Column. Create Doc: Based on the month, the script must be able to create a Google Doc in Essays/MONTH directory based on the client's name and then link it to P Column.
