Adding thread prefix to last post in node list


Active member
I'd like to display the thread prefixes before the title in the nodeLastPost divs in the node list.

I already found out how to change the width of the Node Last Post, and found where to add the prefix in the node_forum_level_2 template. But I can't figure out the code I need to put there.

I tried adding {xen:helper threadPrefix, $forum.lastPost.prefixId} before {xen:helper wordTrim, $forum.lastPost.title, 30} but nothing is displaying.

Does anybody know the correct code to put there please?
