ok im guessing that you want to make it so when you run a report it prints all of the records that Are of a specific Body shell, and are NOT rented between certain dates?
This means you are going to need to have a table with vehicle vin and rented dates both of which can't be primarys
i,e,
|VIN | Date Rented From | Date rented too|Shell|
________________________________________________
| 34224| 23/04/04 |28/04/04 | van |
|34224| 02/05/04 |04/05/04 | van |
|______|__________________|______________|_______
And the Query is
under shell purely the type
under date rented from NOT=> (equal to the date they want) AND NOT=<(date they want to finish)
im not sure on the syntax of ACESS as its under powerd but i would personally do it in VB/s
hope that helps?
