Fetch - FTP transfer error

Hi all.

I’ve written a script, to send a file to numerous routers. On those routers there are running scheduled scripts, that cyclicly check if the file is on the router, then it executes that file, which is a script. All works as it should untill there is an error either connecting to FTP or I get unknown FTP command or something similiar. If I try again it goes through.
OK, let say that the line is not very stable and that the VPN drops from time to time. What I need to know is, is there anyway I can tell the script to ignore FTP errors and continue executing the FTP push command to the next router? Otherwise it stops with error.

Any help apreciated.
