Archive log missing

Hi everyone.  I am testing right now so I'm not worried about missing archive logs. 

My question is:  Because I have an archive log missing, the backup scripts (below) is not deleting my archive logs as it is supposed to. 

.....

 execute script archive_log_switch;
  execute script archive_validate;
  backup database
  plus archivelog delete input
  tag 'backup_full'
  skip inaccessible;
}
exit;
EOF

The log file below shows it is executing the delete command for archive logs but after the backup is done all the archive logs are still there.  I have not been able to regenerate the error about the one archive missing.  How can I tell RMAN to ignore the log that is missing and resume normal operations and delete the backed up archive logs.
