Modeling Career Help?

[van Dorn]

I am trying to create a modeling career, but I am stuck on steps 22-23 of this tutorial (http://nraas.wikispaces.com/Careers+tutorial)
What does this mean? Can somebody help? I am using Packer, and have attached the unfinished package. The sim can join the career, but the interaction is JoinCareer15774283986431767482, and there is no text or description.

Having the same problem as this guy:

But I don't understand how he fixed it.

If you read through the entire thread, Twallan gives advice on how to fix it. Give that a shot and try following those instructions. :)

I don't know where to find the STBLs, and how to change their Instance. I also don't understand what "fill in the values" means. That is why I could not follow the solution on the thread.

I used a different tutorial so I think this is a little better, but I still need help. Largely, this is so that feyerin can help, but others' aid is welcome too!
