I'm sure I am overlooking something here but I am trying to change the FocusBorderColor based on 3 conditions. Right now I have this which I though was going to be fine except that when you focus the field and it is blank the border is DarkRed.
If(Self.SelectedDate <= DP_StartDate.SelectedDate && (FRM_Main.Mode = FormMode.New), DarkRed ,REC_CtrlSelBdrColor.Fill)
What I need to be able to do is add a condition that makes sure that the FocusBorderColor remains the same if the date picker is also blank. I've tried adding an additional condition this way but it fails: && !Blank(Self.SelectedDate)
