Editing Kirupa's External Text Loader&Scroller?

Hi,

i have followed the tutorial on how to load external text and scroll it inside the text area.

i wanna know how can i use this if its not in my main timeline, if its inside a Mc ?

loadVariablesNum("./text.txt", 0);

How can i tell it to load in my Mc ?

thx alot in advance !
