Sounds like you need three tables: Volunteers, Children and Groups. How you structure your groups will determine the relationships needed to link the three tables.
Can a volunteer be a member of more than one group? (Even if it's one group this year and a different group next year...)
Can a child be a member of more than one group? (And again, this may be one group today and a different group some time in the future...)
Yes that's possible..
But i needed the Bento forum.. i accidently posted this on the wrong forum.. im so sorry!
Thank you for making the example file, but as said in the above.. i wasn't paying attention when posting it in the forum.
And i just saw that there are two forums, on which you can post.
So thank you for your help, but i posted this also in the bento forum, i hope they can help me as good as you guys did.
