need to assign it a unique ID if you want to attach a variable to the control so that
you could dynamically alter the text on the control.
The application behaves in a somewhat unpredictable way if you try to alter any of
the static controls that share the same ID. As a general rule of thumb, you can
allow static controls to share the same object ID if you are not going to alter the
controls at all. If you might need to perform any interaction with the controls, then
you need to assign each one a unique object ID.
