I have a range of dates in one column, I need to prioritise against these
dates. For example, in order to define a priority if I have a date of the
12/02/05 and a date of the 25/03/05, then the earlist date is a priority 1
etc. There are around 30 different dates, so the priority number will go up
to 30 (in this case, where the same date exists they will have the same
priority number). Does anyone know of a way of doing this?

Thanks
