PHP While Loop drop down menu problem

I have this problem with a while loop that keeps returning the first initial of someone's name when it runs. I want the full name. The loop is designed to create a drop down list that works fine, except for this stupid inconsistency. I checked the database, and the full name is definitely there. The last name comes out fine, so I dont know where the problem is. Here is the code:

$resulttwo=mysql_query("SELECT * FROM employees WHERE empnum>=1 ORDER BY firstname ASC") or die(mysql_error());

$displayth ='<select name="th" id="th">';

$p=0;

while ($rowtwo=mysql_fetch_array($resulttwo))
{
$empid[$p]=$rowtwo['employeeid'];
$firstname[$p]=$rowtwo['firstname'];
$lastname[$p]=$rowtwo['lastname'];
$displayth .='<option value="' . $empid[$p] . '">' . $firstname[$p] . " " . $lastname[$p] . '</option>';
$displayth .= '</font><font size="2" face="Eras Demi ITC">';


$p++;
}
$displayth .='</select>';

echo $displayth;
