If I do as I think you suggested here:

My  correction snippet based on that here:

{
$sql_events = mysql_query("SELECT * FROM area36 WHERE zipcode  
='$key'") or die (mysql_error());
if (mysql_num_rows($sql_events) !== 0)
{
while ($row = mysql_fetch_array($sql_events)) {
	$dist = $row['dist'];
     $day = $row['day'];
     $town = $row['town'];
	$time = $row['time'];
	$place = $row['place'];
	$street = $row['street'];
	$type = $row['type'];
	$Special = $row['Special'];
	$hca = $row['hca'];
	$ns = $row['ns'];

     //row count for alternating colors

     $row_color = ($row_count % 2) ? $color1 : $color2;

     //create tables for data row loop

     echo "<tr>
	<td class='$row_color'>$dist</td>
     <td class='$row_color'>$day</td>
     <td class='$row_color'>$town</a></td>
	<td class='$row_color'>$time</a></td>
	<td class='$row_color'>$place</a></td>
	<td class='$row_color'>$street</a></td>
	<td class='$row_color'>$type</a></td>
	<td class='$row_color'>$Special</a></td>
	<td class='$row_color'>$hca</a></td>
	<td class='$row_color'>$ns</a></td>
     </tr>";

     // Add 1 to the row count

     $row_count++;
}
}
// error statement if no locations are found within search radius
else {
echo 'Sorry, your search returned no locations.  Try using a larger  
radius to search.';
}



Returns the error statement each time there is an x amount positive  
result.  This was the exact problem I was having.  So what I get is  
the error repeated x amount of  times than my table is built with the  
actual results.  What am I missing?
