Parse error: parse error, unexpected T_STRING in /www/.../private.php

[Dark Jim]

I have no idea what causes it, not even what hack may cause it as I'm not the only one who modifies the code on the forum this occurs. This is the entire error:

Parse error: parse error, unexpected T_STRING in /www/...../private.php on line 315

This is the part in private.php:

PHP Code:

// ############################### start show message ###############################
if ($action=="show") {
  makeforumjump();

  $privatemessageid = verifyid("privatemessage",$privatemessageid);

  $message = $DB_site->query_first("SELECT privatemessage.*,icon.title as icontitle,icon.iconpath,attachment.attachmentid,attachment.filename,attachment.counter
                                    FROM privatemessage
                                    LEFT JOIN icon ON (privatemessage.iconid = icon.iconid)
                                    LEFT JOIN attachment ON (attachment.attachmentid = privatemessage.attachmentid)
  if ($message[userid]!=$bbuserinfo[userid]) {
    $idname="privatemessage";  // This is line 315
    eval("standarderror(\"".gettemplate("error_invalidid")."\");");
    exit;
  } 


Could someone help please?
