Here is the first 77 lines of the script. But how do I fix? 77 references stdnse.keys file. I wonder if that file is missing or missing "keys". Or do I change the name of the file to "variable.keys"

-- | VULNERABLE:
-- | The Heartbleed Bug is a serious vulnerability in the popular OpenSSL cryptographic software library. It allows for stealing information intended to be protected by SSL/TLS encryption.
-- | State: VULNERABLE
-- | Risk factor: High
-- | Description:
-- | OpenSSL versions 1.0.1 and 1.0.2-beta releases (including 1.0.1f and 1.0.2-beta1) of OpenSSL are affected by the Heartbleed bug. The bug allows for reading memory of systems protected by the vulnerable OpenSSL versions and could allow for disclosure of otherwise encrypted confidential information as well as the encryption keys themselves.
