Upload File using TidHTTP with aspx script

Make attached Delphi 2010 code (using Indy 10.5.5) work as expected. Job is to call an aspx script to upload a file to a website. Attached code runs but file does not appear on the site, whilst using the html version calling same aspx works as expected. See attached source code for exact scripts. I would not pay a milestone in advance. Send working exe, if price is good we will pay milestone for source code. You may include some limitations in demo exe. Please do not send resume.
