Again, I am new to LUA but I do understand the concepts from other languages, but this is a completely new syntax for me, I'm used to C-style languages, so forgive me if I am literally standing on the answer

Right now, your XML file isn't passing any of the parameters for the event handlers. Using the old style is tricky since it wraps the handler with a function that has prenamed parameters. You can bypass this by using the function="func" attribute for the script tag.
Here's an example.
Code:
<OnLoad function="hMana_OnLoad"/>
<OnEvent function="hMana_OnEvent"/>
Note this is not a function call, it's simply grabbing the pointer to the function and setting the script handler to it. The function MUST EXIST at the time you make this assignment otherwise the handler will never run (the function referenced will be nil).
