Upon doing some xhtml validating today your code came back errored. The issue is with the ids on divs. You can not have an id or class starting with a number. A simple change to place the post number at the end and a javascript edit and it was valid.

id="$post[postid]postbittabs
changes too
id="postbittabs$post[postid]

and

var mytabs=new ddtabcontent("$post[postid]postbittabs")
to
var mytabs=new ddtabcontent("postbittabs$post[postid]")
