That is, ni > fact, one of the cardinal rules of Relational Database Design. Well, I started with "I'm a beginner". But I'm sure there's no reason NOT to accept two records that are exactly the same. In the example I gave, it is clear that the information I want to store can contain two records that are exactly the same; doing the same thing, on the same day, for the same amount of time. In this case it is the technical structure that doesn't want it like that. So I have to change it to make it work. Fons. fonzzz@xs4all.nl
