Adding a Moveclip to the Screen that uses .as code ? [AS3]

Hello everyone,
I am having trouble accessing this movieclip and adding it to the stage.
I have just started using external .as files to code game characters and this is the only part that gets me at the moment.

The character works completely fine if they are already on the stage when the frame loads, but I cannot figure out how to access this movieclip and place it on the stage from the MAIN timeline, where I plan on running the main game code.

I have tried tons of variations, is there anyone that can please tell me the proper way to do this with this linkage? Thanks in advanced!
