Creating an inventory summary by months

[Mazkot]

Hello all,

I am creating a inventory database for a bee keeper where he will keep track of the number of hives (along with sorted other things bee keepers track). He would like a layout which will show him by month what his ending count of total hives is. SO my problem is how to summarize across many locations the final count of all hives. Some locations will have many counts for a particular month while others may only have a few. The basic structure is as follows:

Table: Locations

Field: _LocationIDpk

Field: Location Name

Table: Inspections

Field: _LocationIDfk

Field: Date

Field: Hives_count

He will use this to track the loss of his bees over time.

Any suggestions are greatly appreciated.
