    Pull data from one table and calculate and post into field in another table

    I have a subform where I enter the date someone attends a meeting and then this information flows into my table "Meeting Dates". I want to take this information from Meeting Dates and count the number of times an individual attends a meeting during a specific year and then have this data fill in the appropriate field in my "Attendees" table. For instance: AttendeeID = 64, 2020 Attendance = 3

    "Attendees" Table: Primary Key = AttendeeID, Field to drop data into "2020 Attendance"
    "Meeting Dates" Table: MtgDates, AttendeeID

    I found something online and thought it could work.
    SELECT T1.Employee_ID,
    (SELECT COUNT(*) AS CNT FROM Employees AS T2 WHERE T2.Manager_ID =
    T1.Employee_ID) AS Supervised_Count
    FROM Employees AS T1;


    Now, if I could just figure out where to plug my data into.
    SELECT MEETING DATES.AttendeeID,
    (SELECT COUNT(*) AS CNT FROM XXXX WHERE XXXX = XXXX) AS 2020 Attendance


    FROM XXXX AS XXXX

    HOWEVER.. if this isn't going to work let me know what might. : )

    Create a totals query based on your MeetingDates (suggest to not use spaces in field or object names in Access) in which you Group By AttendeeID, Year([MeetingDate]) and Count([MeetingId]). That will give you a nice summary for each AttendeeID and Year. I suggest you do not store that in your other table but rather get the info from this query as needed (for example you can use a dLookup in a form to get the record matching the AttendeeID and Year).

    Cheers,
