Add a function to your form, see below: -
' -------------------------------------------------------------------------
Private Function CheckBoxCheck()
Dim tmpmsg As String
tmpmsg = ""
If Check01.Value = -1 Then
tmpmsg = tmpmsg & "Check Box1" & vbCrLf
End If
If Check02.Value = -1 Then
tmpmsg = tmpmsg & "Check Box2" & vbCrLf
End If
If Check03.Value = -1 Then
tmpmsg = tmpmsg & "Check Box3" & vbCrLf
End If
If Check04.Value = -1 Then
tmpmsg = tmpmsg & "Check Box4" & vbCrLf
End If
If tmpmsg <> "" Then
MsgBox "You have checked the following options: - " & vbCrLf & vbCrLf & tmpmsg
End If
End Function
' -------------------------------------------------------------------------
Then on each check box add an on_click event and call the function, it will check to see if the check boxes have been checked and create a statement which can be used by the msgbox function to notify you of which check boxes have been pressed.
' ------------------------------------------------------------------------
Private Sub Check04_Click()
Call CheckBoxCheck
End Sub
' -------------------------------------------------------------------------
Hope this helps
