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.
