When you are in design mode set the visible property to 'No' and name it something like 'lblMessage'. In your macro, when you need to show the label use the SetValue instruction:
Instruction name: SetValue
Item: [lblMessage].[Visible]
Value: True
If you are using VBA then it's:
Code:
lblMessage.Visible = True
. You may need to prepend the name of the form if your code is in a module.
