Using a Substitution Variable

Note the &1 in the No. column; this is the substitution variable that represents the Horse name parameter. You will use this substitution variable to include the selected horse’s name in the text of the message. Recall that you used this process earlier in the tutorial when you defined error messages for the condition that compared a horse’s date of birth with those of its parents.

The original message text is "Racing results displayed." Add "for &1" to the end of this text.
