You're a teacher and you've created a form letter in Word that you send to the parents of the students in your class at the beginning of each year. The letter pulls parents' names and addresses, along with the children's names, from an Excel file you get from the main office. The original creator of the Excel file used a column labeled Father Name and another labeled Mother Name. Over the summer, a new person took over and updated the file. Parent names are now located in columns titled Parent 1 and Parent 2. What do you need to do to make your form letter work with the updated Excel file
