EN scripting issue- unable to use toLowerCase

[Supreme Eagle]

Hi,
I am modifying an existing script (https://forum.sinusbot.com/resources/mail-system.211/) for my Ts3server and I have hit a roadblock with it.
(link for the script [MODIFIED] = https://pastebin.com/acy7p7p8 )

Issue with the old script was that it was created before the new engine was released and I am trying it to make it work with the current version of the sinusbot.

The error I am facing is TypeError: Cannot access member 'toLowerCase' of undefined.
and Cannot access member 'split' of undefined .

Any help would be appreciated.

ps (I am a complete noob with the JS i know C and C++).

This means that the variable you are calling the methods on is not defined.
