Calculating on Previous Record Field

[SamanthaW]

I have a report that groups a property with any leases it has had during a given period. How can I calculate the days the property was vacant based on a field in the previous record's lease vacating date and the next lease start date, i.e.:

Property
Lease 1 Start Date / End Date /
Lease 2 Start Date / End Date / Days Vacant = [Start Date] - [Lease 1 End Date]
Lease 3 Start Date / Days Vacant = [Start Date] - [Lease 2 End Date]

There is no limit to the number of leases a property might have.

I would use a subquery in the report's record source query to get the previous dates.

Thanks, I ended up dusting of my rusty MS Access code skills and wrote"on print" code that stored the value of the previous lease vacation date and calculated this with the current lease start date an passed the result into a custom field value in the report.
