Download Lock Counter Extension Error

There is a Download Counter extension out there that works in conjunction with the Download Lock module. It ships with an error on line 80:

Parse error: syntax error, unexpected ‘=’ in
/site/system/extensions/ext.custom_download_count.php on line 80

The lines in that area look like:

else
  {
  tdata = array($data['t'], $data['mt']);
  $mid_sql = $data['t'].', '.$data['mt'];
  $sql = "UPDATE exp_weblog_data SET ".$mid_sql." WHERE entry_id = $entry_id";
  $DB->query($sql);        
  }

Has anyone successfully used this extension with Download Lock? Did you change line 80 from tdata to ‘$data’ or ‘$tdata’ or ‘$sdata’? The PHP right in that area is still a little beyond my immediate comprehension. Thanks for any help with this module/extension.

And while we’re on the subject, has anyone seen my post on the old Download Lock thread with a slew of questions relating to Download Lock itself?
