I dont know jack about LUA and I don't know if nil is anything like null but null means "no value". note that this doesn't mean 0, but rather that there is no value at all. In this case it means that either your function returns nothing, or that the function doesn't exist within the scope of how you're using it. Check to make sure that the function has been properly declared, that you're spelling it right, or that you're allowed to use it in the context of how you're using it.

edit: in the future, take your error log, copy the first line or so and paste it into google to see if other people have had your problem. That's why the error log exists

in this case it's:

attempt to call method 'ScreenFade' (a nil value)
