Answer:
<form action="zip-it.php" method="post">
<p>Please enter your zip code:
<input type="text" size="20" name="zipCode"></p>
<input type="submit" value="Submit your zip code">
</form>
Step-by-step explanation:
Both input elements (Textboxes) are wrong because they lack the "/" character that should be placed just before the ">" character. The form tag is correct, it correctly points to the script which is the value of the action attribute and had specified that the method to be used is post. The paragraph tag (p) is also correct.
