You create a new cfm page whose responsability is only to display the post...lets call it display.cfm.
This page needs the ID of the post...an ID that is related to the database entry (can be you primary key in the table that you are storing the posts).
All you have to do for this page to have the necessary info to display the post is pass a parameter in the URL (called query string)...something like this <base_url_here>\display.cfm?id=1
You get this ID...select the post with this ID from the database and you are done.
In your main page, you must create the link to this page dynamically as the id will change for every entry.
So the display page is allways the same but the contents change according to the ID passed in the query string.
Regarding the five post display....
You can do it in the select to the database...or if you have an array of entries you display only the first 5
Then you have a link...to the same page perhaps with a different query string that displays all of them....
If you have any other doubts just ask.
It worked so well, thank you very much.
