Multi Quote & Quick Reply Problem

One of my members just informed me that there is a problem with the Multi Quote and Quick Reply buttons in posts. On looking into it, they are only working in the first two posts of a thread :confused: That doesn't make sense. Any help appreciated :)

hmmmmmmmm I figured this out easy enough in the end. I had edited the post_legacy template by adding to the end of the template the code to have ads after the post in a thread and this was what interfered with the 'quick reply' and 'multi quote' buttons in every post from the third on. That's a shame as I had wanted the ads in every thread, but my members also need the 'multi quote' capability in particular. For now I have taken out the code for the ads. Does anyone know of any way to work around this? I used the code here http://www.vbulletin-faq.com/forum/showthread.php?t=4697&highlight=post
