Need a script for user password change

[phongvucba]

1. Upload attached pass.lp and pass.lua to user directory via FTP (more info here: https://forum.logicmachine.net/showthread.php?tid=85)
2. Make sure that "Enable password for User directory" is set in User access > User access settings
3. Place iframe in visualization, set URL to /user/pass.lp
4. Test with normal user, admin password cannot be changed this way
5. You can edit pass.lp and translate labels and error messages there

Has anyone done this yet?
I also followed the instructions, using FileZilla ftp software on LM3 (2 files in the tutorial)
But it does not find the file
Where do I go wrong?
