I need to put something together that would keep the previous state of a field in another field, as well as a change date.

For ex, let's say we have the field price, i would want a field named, say oldPrice, which would hold the value of the field before it was last changed and a priceChangeDate field which would hold the date and time of change.

initial experiments with calculations haven't gotten me anywhere just yet...

anybody have any pointers?

If I'm understanding your correctly, you are describing creating an Audit Trial, often referred as Field Modification Tracking.
