Cron FTP job

We have a script that we run manually, we want to set it up so that it will run automatically via cron, the problem is during the ftp process nothing is put, the script logs in changes directory fine, but nothing is put to the directory. I have tried it as root, a power user, etc. I have made the file 777, etc etc...but it will not put files.
Any ideas, questions or comments would be greatly appreciated..
thanks

Post the OS and versions of the servers involved (specify which is which) and post your script. Or use the Search button at the top of the web page and search for ftp and automated.

hi
you should check the size of the disk in the server and permission given to the user you are logging in as ,if u have to put multiple files at a time,turn off the interactive mode

post your script code. it will help to check if anything is wrong.

post the script to analyze it...
