Alice has another selection list to add to the survey form, recording where the cus-
tomer heard of Red Ball Pizza. The survey presents the user with five options: the
Internet, a magazine, a newspaper, word of mouth, or other. Alice wants you to display
all of the options by setting the value of the size attribute to 5.
To set the selection list size:
1. Return to the survey.htm file in your text editor and add the following label and
selection list directly below the email field (see Figure 6-31):
<label>Where did you hear about us?</label>

<option value=”mag”>Magazine</option>
<option value=”news”>Newspaper</option>
<option value=”word”>Word of Mouth</option>
<option value=”other”>Other</option>
