In the attached code, I am trying to reference a hash contained in an array. However, each time I try to reference the hash, it says it is not a Hash. I'm following the examples with no luck. Can you help? Specifically with the ftp_sessions() array. Thanks This code is being put together to monitor multiple, long-running FTP jobs. I don't have that code in here ... basically stubbing it out with sleep statements.
