ftp latest file retrieval macro

[LEG_END]

Hi,

I am trying to retrieve the latest file from an ftp site.

This is the code I have pretty much copied from another thread to be honest but appears to work and returns no errors however it doesn't return any files nor does it put them in the folder I choose can anyone see any issues?
