Don't be shy ;-), show us your script.

No you couldn't. A single ampersand, the control operator '&', means that
the command preceding it will be executed in a subshell in the background.
It will then go on and execute the next command regardless of the first
command's status. You want to use the control operator '&&', i.e. AND,
which will execute the second command only after the first command is
executed with an exit status of zero.

For more information have a look at 'man bash'.

Also have a look at 'man ncftpput' if you really have to use FTP,
otherwise try 'man ssh' and 'man scp'.
