Mini Fix.

Replace

PHP Code:

<script language="JavaScript">
function confirmdelete() {
  messagebox=confirm('You have chosen to delete Post  $post[postid].\r\rClick OK to delete it, or Cancel to hide this prompt.');
  if (messagebox==true) { window.location='editpost.php?s=$session[sessionhash]&action=deletethispost&postid='$post[postid]; }
  else { }
}
</script> 


with

PHP Code:

<script language="JavaScript">
var postid;
function confirmdelete(postid) {
  messagebox=confirm('You have chosen to delete Post ' + postid + '.\r\rClick OK to delete it, or Cancel to hide this prompt.');
  if (messagebox==true) { window.location='editpost.php?s=$session[sessionhash]&action=deletethispost&postid=' + postid; }
  else { }
}
</script> 


and then replace

PHP Code:

<a href="javascript:confirmdelete()">Delete Message</a> 


with

PHP Code:

<a href="javascript:confirmdelete('$post[postid]')">Delete Message</a> 


The popup should work fine now if any of you had problem with it.
