Creating new row in a different model from within a drawer

This is very strange. I have tried everything I can think of to get the proper data to pull. My last attempt was working with only 1 model thinking that had something to do with it. It didn’t it still only sees what parent line.  

The only thing I could get to remotely work was using a merge syntax to pull directly from the line item model. However that only pulls the first line and not all lines in the model.

I am just spinning my wheels at this point… I am out of ideas…
