First, please keep discussions on-list unless otherwise requested. It's bad etiquette (and a good way to get ignored) to contact someone directly and off-list : 1) It assumes they have the time to provide you with personal, one-to-one, assistance. 2) It assumes no-one else can help. 3) It assumes no-one else (including anyone searching the archives in the future) could benefit from the assistance given. Which is nothing whatsoever to do with RRD. That's a simple data problem. I'm not going to do your coursework for you, but you need to study the database documentation - and since it's MySQL then you need to look at the syntax for the "WHERE" clause. And in fact, you've already given half the answer above - the test condition is "ID = 4". -- Simon Hobson Visit http://www.magpiesnestpublishing.co.uk/ for books by acclaimed author Gladys Hobson.
