syntax error

Hi Karen, The url to the site is gtebooks.com
the url to the admin is gtebooks.com/admin
When I try to log into the admin page, that is
when I get the error code.

I went to the cpanel and tried to find the problem
that way but I'm not sure what to look for.

I don't have a back up of the file. the one I was in
when I clicked save was the box.php file.

What should I look for?

OK here it is

<?php
/*
Example usage:

$heading = array();
$heading[] = array('params' => 'class="menuBoxHeading"',
'text' => BOX_HEADING_TOOLS,
'link' => tep_href_link(basename($PHP_SELF), tep_get_all_get_params(array('selected_box')) . 'selected_box=tools'));

$contents = array();
$contents[] = array('text' => SOME_TEXT);

$box = new box;
echo $box->infoBox($heading, $contents);
*/

class box extends tableBlock {
function box() {
$this->heading = array();
$this->contents = array();
}

function infoBox($heading, $contents) {
$this->table_row_parameters = 'class="infoBoxHeading"';
$this->table_data_parameters = 'class="infoBoxHeading"';
$this->heading = $this->tableBlock($heading);

$this->table_row_parameters = '';
$this->table_data_parameters = 'class="infoBoxContent"';
$this->contents = $this->tableBlock($contents);

return $this->heading . $this->contents;
}

function menuBox($heading, $contents) {
$this->table_data_parameters = 'class="menuBoxHeading"';
if (isset($heading[0]['link'])) {
$this->table_data_parameters .= ' onmouseover="this.style.cursor='hand'" onclick="document.location.href='' . $heading[0]['link'] . ''"';
$heading[0]['text'] = '&nbsp;<a href="' . $heading[0]['link'] . '" class="menuBoxHeadingLink">' . $heading[0]['text'] . '</a>&nbsp;';
} else {
$heading[0]['text'] = '&nbsp;' . $heading[0]['text'] . '&nbsp;';
}
$this->heading = $this->tableBlock($heading);

$this->table_data_parameters = 'class="menuBoxContent"';
$this->contents = $this->tableBlock($contents);

return $this->heading . $this->contents;
}
}
?>

Thanks for your help
