Anyone have any ideas?
Could you supply your values to the final view using parameters in your final dataview? I believe you can pass parameters through web part connections as well.
I have 3 parameters which I've gathered from web part connection to web part connection in the first 3 data views. The problem is passing those parameters along to the edit function within the last data view so they can be saved in the last list.
You didn't by chance find a solution for what you were trying to do?
I'm trying to do something similar.
