infoBox is hanging the page

[Weirfire]

My osCommerce site is very modified but this problem doesn't appear to be related to the modifications I've added so thought I would post this and see if anyone else has had the same problem.

 

On a number of different sub categories the infoBox class appears to be hanging the page.

 

I get the search heading but not infoBox below it.

 

If I remove the code for the search box then I get the categories heading but no categories.

 

Everything works fine for all the other categories.

 

Below is the code for my /includes/classes/boxes.php page;

 

  class tableBox {
var $table_border = '0';
var $table_width = '100%';
var $table_cellspacing = '0';
var $table_cellpadding = '2';
var $table_parameters = '';
var $table_row_parameters = '';
var $table_data_parameters = '';

// class constructor
function tableBox($contents, $direct_output = false) {
  $tableBox_string = '<table border="' . $this->table_border . '" width="' . $this->table_width . '" cellspacing="' . $this->table_cellspacing . '" cellpadding="' . $this->table_cellpadding . '"';
  if ($this->table_parameters != '') $tableBox_string .= ' ' . $this->table_parameters;
  $tableBox_string .= '>' . "\n";

  for ($i=0; $i<sizeof($contents); $i++) {
	if ($contents[$i]['form']) $tableBox_string .= $contents[$i]['form'] . "\n";
	$tableBox_string .= '  <tr';
	if ($this->table_row_parameters != '') $tableBox_string .= ' ' . $this->table_row_parameters;
	if ($contents[$i]['params']) $tableBox_string .= ' ' . $contents[$i]['params'];
	$tableBox_string .= '>' . "\n";

	if (is_array($contents[$i][0])) {
	  for ($x=0; $x<sizeof($contents[$i]); $x++) {
		if ($contents[$i][$x]['text']) {
		  $tableBox_string .= '	<td';
		  if ($contents[$i][$x]['align'] != '') $tableBox_string .= ' align="' . $contents[$i][$x]['align'] . '"';
		  if ($contents[$i][$x]['params']) {
			$tableBox_string .= ' ' . $contents[$i][$x]['params'];
		  } elseif ($this->table_data_parameters != '') {
			$tableBox_string .= ' ' . $this->table_data_parameters;
		  }
		  $tableBox_string .= '>';
		  if ($contents[$i][$x]['form']) $tableBox_string .= $contents[$i][$x]['form'];
		  $tableBox_string .= $contents[$i][$x]['text'];
		  if ($contents[$i][$x]['form']) $tableBox_string .= '</form>';
		  $tableBox_string .= '</td>' . "\n";
		}
	  }
	} else {
	  $tableBox_string .= '	<td';
	  if ($contents[$i]['align'] != '') $tableBox_string .= ' align="' . $contents[$i]['align'] . '"';

  }

  $tableBox_string .= '</table>' . "\n";
