Whenever I submit the search on the previous page, it goes to this page (as it should), but the code will not execute and I just end up with a blank page.

===================================================== 
<? 
// perform search only if a string was entered. 
   { 
    mysql_connect() or die ("Problem connecting to Database"); 

    $query = "select * from pet WHERE pet_species like '$search'"; 

    $result = mysql_db_query("mydb", $query); 

    if  ($result) 
    { 
echo "<table border=1 width=75%>\n"; 
echo "<tr><td align=center><b>Pet Name</b></td><td align=center><b>Owner Name</b></td><td align=center><b>Pet Type</b></td><td align=center><b>Sex</b></td><td align=center><b>Birth Date</b></td></tr>\n"; 
do { 
printf("<tr><td>%s</td><td>%s %s</td><td>%s</td><td align=center>%s</td><td>%s</td></tr>\n", $myrow[pet_name], $myrow[owner_first], $myrow[owner_last],$myrow[pet_species],$myrow[sex],$myrow[pet_birth]); 
} 
while ($myrow = mysql_fetch_array($result)); 
echo "</table>\n"; 
} 
else { 
echo "Sorry, no records were found!"; 
} 
?>
