Please help, it'll only take a second ;)

I want to make a link inside the postbit area of each member that, when clicked, will direct you to that users newest post.

I thought making a link to this would work:
showthread.php?s=$session[sessionhash]&postid=$getlastpost[postid]#post$getlastpost[postid]

For example, in the post bit putting:
Newest Post: <*a href="showthread.php?s=$session[sessionhash]&postid=$getlastpost[postid]#post$getlastpost[postid]">Here</a>

But it didn't work

So what can I do to get the link to work?
