I had forgot to include the Post id's in the post bit template, Because the theme has been stripped down so much i didnt realise they had been removed.
Added this back into the post bit and it seems to have solved my issue :
Code:
<a name="post{vb:raw post.postid}" href="{vb:link thread, {vb:raw thread}, {vb:raw pageinfo_post}}#post{vb:raw post.postid}" class="<vb:if condition="$show['inlinemod']">ie</vb:if>postcounter">#{vb:raw post.postcount}</a><a id="postcount{vb:raw post.postid}" name="{vb:raw post.postcount}"></a>
