[Plugin: Shortcode Exec PHP] Error messages – how to interpret

Here is the code:

extract(shortcode_atts(array('arg' => 'default'), $atts));

$playerID = $arg;

$dbbosfan = mysql_connect ("localhost", USERNAME, PASSWORD);
if (!$dbbosfan){
	die ('I cannot connect to the database because: ' . mysql_error());
}

mysql_select_db ("bosfan_redsox",$dbbosfan);

$query = "SELECT * FROM playerdata pd WHERE pd.playerID = '$playerID'";
$result = mysql_query($query,$dbbosfan) or die(mysql_error());
$row = mysql_fetch_array($result);

$p_name = $row['fullname'];
$p_byy = $row['byy'];
$p_bmm = $row['bmm2'];
$p_bdd = $row['bdd'];
$p_posID = $row['posID'];
$p_pos = $row['pos'];

$p_legend = FALSE;
if ($row['legend'] == TRUE){
	$p_legend = TRUE;
}

$p_soxhof = FALSE;
if ($row['soxhof'] == TRUE){
	$p_soxhof = TRUE;
	$p_soxhofyear = $row['soxhofyear'];
}

$p_bbhof = FALSE;
if ($row['bbhof'] == TRUE){
	$p_bbhof = TRUE;
	$p_bbhofyear = $row['bbhofyear'];
}

mysql_close($dbbosfan);

print "  <p><strong>Date of Birth</strong>: ".$p_bdd." ".$p_bmm." ".$p_byy."<br/>\n";

if ($p_soxhof = TRUE){
  print "    <strong>Elected to Red Sox Hall of Fame</strong>: ".$p_soxhofyear."<br/>\n";
}

if ($p_bbhof = TRUE){
  print "    <strong>Elected to Baseball Hall of Fame</strong>: ".$p_bbhofyear."<br/>\n";
}

print "  </p>\n\n";

Resolved it… apparently, it did not like the use of the mysql_close() fuction.
