one can set the 'noError' variable to ignore any errors that occur for the next command. However, the code was only unsetting 'noError' when an error actually occurred, so if you set 'noError', the next command completed ok, and the command after that failed, the second command's failure would be ignored. This fixes this by performing the 'noError' check earlier and then unsetting 'noError' after every command that is run. Sponsored by: The Weather Channel
