Can anyone help with some issues I'm having around cases?

1) I'm using mixed methods and have interview transcripts (assigned to a case per participant) and a survey (each row automatically assigned a case on uploading and attributes added to the cases from my quant responses). Respondents that have interviewed were manually assigned to the same case as their interview transcripts. The two sources are counted on the case list. But, the attributes that were automatially assigned via the survey data, have not gone over to the interview case.How can I do this?

2) I want to do quite a bit of work on cases in my survey data - e.g. how many cases referred to X node. It gives source as 1 of course and references are counted but that's unreliable if a participant (case) has been coded for a node more than once in different questions. Why can't case be simply added in the node window alongside source and references to be tallied? I'll want to do matrices too that count participants (cases) against atttributes and nodes. I ran a query against cases adn a selection of nodes and every box said 0 and even if it hadn't it would make no sense to then ahve to manually add up the columns.

This need to work with cases seems obvious so I must be missing something in the nVivo functionality.
