Login Path

I’m trying to create a login using this script method:

The script works great running the movie on it’s own, but when I load the movie in from a a parent movie, I’m only able to send data. I know the problem I’m having has to do with the paths, but I can’t seem to figure out how to get back to the logged in state no matter how simple the parent movie is. Can someone explain how I would get verification of the logn and jump to the correct frame?
