You are trying to reference a thread from the threadbit. To my knowledge you must first reference a specific thread before calling any of its information.

Let me see what I can find out for you.

Well mate, I can get everything to work except the display of the 'attachmentid'. If someone can chime in on how to display the attachmentid then this will work just fine. You need to modify your code to look like:

PHP Code:

<a href="attachment.php?$session[sessionurl]attachmentid=$attachment[attachmentid]&amp;d=$thread[dateline]">TESTING</a> 


Some key things to keep in mind:
-What happens when there are multiple attachments?
-In your original code, you did not have the HTML correct to even display anything, you only posted a link.
-In the future, please remember, when you are calling thread information you must refer to them with "$thread".

Hope I was able to help

// Edit //
I don't have the time to modify that, however that will display on every thread, regardless if there is an attachment. That must be modified to an IF statement to display/hide if there is/isn't an attachment. If I have time I will code and post.
