I have a form (form #1), which contains a field named txtGrowDaysCalc.

And in that form I have a subform named subfrmReady.  When Form #1 opens and if the field txtGrowDaysCalchas no data in it then I want a message box to appear before the user can enter data in the subform.

Here is my onopen event of the subform which isn't working.

   If IsNull(Forms!frmPlanted.txtGrowDaysCalc) Then
        MsgBox "You must select a Grow Days checkbox."
   End If

On the main form, select the subform object and set an On Enter event to display the message box if the text field is empty.  When the subform gets the focus (user clicks into it) the On Enter event will fire.
