In may be evident to others, but the following items caught me while trying to create TrueUpdate Action scripts using FTP:
1) Ensure if you are using long filenames that your files do NOT have any embedded spaces. Replace spaces with an underscore if you want to maintain readability.
2) FTP servers I have been using have the username as the default directory. So if you are setting up TrueUpdate FTP actions rather than using /update as the "Remote site folder" you may have to use /<username>/update, where <username> is of course your FTP username.
