How to sum records between two dates on a form?

[Emaline]

I am responsible for tracking training hours each year for a number of employees.

I have just developed a database that includes both the fields "date" (of training) and "hours" I want to sum the hours of training for each year. Say <01/01/2010 for this year and for years going forward either >=01/01/2011 and <=12/31/2011 or just >12/31/2010

First, if your field is really named date, I recommend changing it to something else as "date" is a reserved word. Something like TrainingDate would work fine. That said, try this:

I set up a table (YourTableName) and added two columns (hours and TrainingDate). I then created a form with two unbound controls: txtDateYear and txtTotalHours. In the after update field of txtDateYear I have the following code:

Private Sub txtDateYear_AfterUpdate()
 
txtTotalHours = DSum("[hours]", "YourTableName", "[TrainingDate] Like '*" & [txtDateYear] & "'")
 
End Sub 

When you type/select a year from txtDateYear it will automatically populate txtTotalHours with the total number of hours for that year.

Let me know if you have any questions.
