well, first of all : the example code from my last post generates a list of links with the content of your title-colom in it (seperated by a break between each link.) when you click one of them, it calls for the info.asp page and takes an ID with it in the querystring.
(if both the title and content are in the same table, and there is aan ID in this table, say "messageID", you could pass this ID along via the querystring. just replace the "name_of_varible_with_InfoID" then by this "messageID"
if you try it out, and you look at the code when you browse the page, you wll see it generates straigth html (as asp always does).
you can generate this linklist into a floating box by placing this code between the div-tags. (as if you would insert it manually)
i don't know about your scrolling part. how do you make them scroll ? i suppose you use a small script to let the content of the floating box scroll, so i expect it would still work with this generated list.
