Thanks for catching my label error and for the suggestion. I ended up doing this:
<?php
$counter = 0;
for ($x = 1; $x <= 5; $x++) {
$counter++;
echo "Student " . $counter . ":";
echo "<div class=\"form_fields_enthusiast\">
<p><label for=\"Name\">Name:</label>
<input name=\"First_Name_" . $counter .
"\" type=\"text\" value=\"\" size=\"16\" maxlength=\"35\" placeholder=\"First\"/>
<input name=\"Middle_Name_" . $counter . "\" type=\"text\" value=\"\" size=\"16\" maxlength=\"35\" placeholder=\"Middle\"/>
<input name=\"Last_Name_" . $counter . "\" type=\"text\" value=\"\" size=\"16\" maxlength=\"35\" placeholder=\"Last\"/><span style=\"font-size:11px\">(Required)</span></p>
<div style=\"display:none\">
<input type=\"text\" name=\"email_address_" . $counter . "\" value=\"\" />
</div>
<p><label for=\"address_" . $counter . "\">Address:</label>
<input name=\"Address_" . $counter . "\" type=\"text\" value=\"\" size=\"25\" maxlength=\"35\" placeholder=\"123 Main Street\"/>
