I believe you are lacking responses on this one due to lack of QVW, as folks likely want to see the expressions and data model etc. to be sure of what they are trying to solve. If you can attach even a subset of the app or a sample app, I would expect that should help, but the other thing I would be sure to do is check the Help documentation to ensure your expectations are inline with that documentation, as if things are working per the documentation, then you need to approach this from are there any workarounds to get what you want, and again, folks will likely need to see an app to be able to help with that from past experience.
To help users find verified answers, please do not forget to use the "Accept as Solution" button on any post(s) that helped you resolve your problem or question. I now work a compressed schedule, Tuesday, Wednesday and Thursday, so those will be the days I will reply to any follow-up posts.
