What do they *mean*? They are just variable names. You can name results anything you want. In vbulletin code, $show is in general used as the variable to determine if something should be shown or not, and $post is in general used for post results.

When will the code be displayed after construct_page_nav is called.

i think i have rewritten the code i early posted and it run's fine, no errors.
But there are no attachments there is only the page header, navbar and footer.
but inbetween where the attachments should be there is nothing ?

what could be wrong ?

I have no idea because I don't know anything about the code.

i have te script running on 3.8.2 but i left some part's out becaus i don't get them to work.

one of them is this peace of code
what is wrong, Canview does that exicst ?

Try doing a search in other vb pages (use a text editor that will search all pages in a folder/directory) for similar code in vb and see what code is used. For instance, I think forumpermissions are usually attached to a forumid now, ie ['forumpermission']['some_forumid'] . So, you'll probably have to play with the code a bit.

edit: OK, I did find a couple of places where that isn't so. Do a search for "$vbulletin->userinfo['forumpermissions']" and you'll find some examples of 3.8 code that is similar to what you have there.
