Hi,
Glad you got the first problem solved 
The script was just designed to make one directory on the remote server and upload a list files to it.
Sub directories would require recursion, which would get tricky.
Can you try this script with just one folder on your local PC which contains only files.
Before running it, please also, make sure that there is no folder of the same name on the remote server (i.e. if your local folder’s name is “test”, make sure that there is no “/test” on remote).
Let me know how you get on.
