Count checked checkboxes

Hello,

On my MS Access form I'm creating an Unbound textbox which I'd like to count the number of check boxes selected in a subform (default view "DataSheet"). I thought if I do =Sum([table].[checkbox])*-1 would work, but that is not the case.

how can I accomplish this?

You have to query the record and COUNT the checkboxes that = true (or not zero).

This should work behind am event handler:

    Dim ctl As Control
    Dim i As Integer
    i = 0
    For Each ctl In Me.YourSubFormName.Controls
        If ctl.ControlType = 106 Then 'The control is a checkbox
            If Nz(ctl.Value, 0) = -1 Then 'do not evaluate null or unchecked
                i = i + 1
            End If
        End If
    Next
   
    Debug.Print i <------Use this however you need it

Im not sure this will work for the Datasheet view...but this is what I would do in a regular form.

Dim ctl As Control
Dim intCount As Integer
intCount = 0

For Each ctl In Controls

If TypeOf ctl Is CheckBox Then
    If ctl.Value = -1 Then
        intCount = intCount + 1
    End If
End If


Next

MsgBox intCount
