Thank you for showing me this module.

After looking through the error log, I was able to figure out if I comment out the following from the tpl_header_currencies.php around line 19, the Dynamic Filter will work without any errors.

I do not know if it is supposed to be like that or not but it works for me right now.

HTML Code:
      $hidden_get_variables = '';
      reset($_GET);
      while (list($key, $value) = each($_GET)) {
        if ( ($key != 'currency') && ($key != zen_session_name()) && ($key != 'x') && ($key != 'y') ) {
  // Comment this out ->       $hidden_get_variables .= zen_draw_hidden_field($key, $value);
        }
      }



After going through the files I found I was able to comment
