Calendar not using nodes, but individual Date CCK inputs?

First of all, really sorry if I've not explained this well enough. I've tried googling the problem but (perhaps due to wrong wording of search terms, etc) I've not found anything related to what I am trying to do.

I've got a node that I've set to add multiple values on for a CCK Date field (with day-based granularity) which is to drive the calendar display - so one value in the node representing one day block in the calendar, rather than one node for example.

The furthest I've gotten so far is to take the default view output by the module, and change the referenced field in the mandatory date argument to the field I'm trying to have the calendar show. This is resulting in an empty calendar.

I'm prepared to accept that this is because my brain is fried (Brits, check the time this issue was created!) but I can't figure it out. I've gotten calendar views to work absolutely fine before when each value was an individual node, but this issue seems to have eluded me.

Ideas? Thanks guys,

Kris
