Help with this code

[Parker Clack]

When I insert

$customrowbanner = $db->query_read("SELECT id,banner_text FROM " . TABLE_PREFIX . "banner WHERE groupid=$foruminfo[forumid] ORDER RAND()");
$id=$customrowbanner['id'];
$text=$customrowbanner['banner_text'];
eval('$custombanner = "' . fetch_template('custombanner') . '";');
} else {
$custombanner = "";
}

in the forumdisplay_start hook I get

Parse error: parse error, unexpected '}'

Any ideas on how to write this to avoid this error message?

Thanks,
Parker
