Thanks for all your help, but my main problem now is, how to show the relationships. I mean, OK, I trace the names in my database, but how to show the relationship to the user, searching for it?
Should I draw a complete tree that means all the people involved between the actual two, or ........ I dont really understand it. Any ideas? Anyway thanx again for your great help.
