Execute script from calc. result automaticaly

[GuyC]

I'm making a dbase to make tooling planification and to know the occupation time of my laser cutting equipement for each day of production.

The problem that i would like to resolve is this one:

I would like to copy the time from a previous record field to the next record field automatically when i enter data in another field containing text data.

I can to this with a script, but i want it to be automatic, to be sure that user's wont forget it.
