bash error handling help

[theal]

I am have a script that uses a for loop to copy files to about 100 servers.
I know how to get it to exit the entire script on an error, but I only want
to stop what it is doing for the current $i and move to the next. here is
the basics of the script. there may be some syntax errors in this script as
I have edited it for public viewing.

Thanks

Tony
