Ok, here's one I'm stumped on! This is simplified a bit, but gets the point across as to what I'm trying to do.

I have a table of records. Each table can have a varying number of child records in a related table. Each parent will have at least one child, but can have an unlimited number after that.

Each child has a field with text entered either "yes" or "no". In the parent record, I want a calculated field to return "yes" if every child record says "yes" and otherwise return "no."

So:

Child 1 = "no"

Child 2 = "no"

Parent = "no"

Child 1 = "yes"

Child 2 = "yes"

Parent = "yes"

Child 1 = "yes"

Child 2 = "no"

Child 3 = "yes"

Parent = "no"

Any ideas?

Make a calculation field in Child of field = "yes". This calc will return a 1 for all 'yes'es. Make a calculation field in Parent of Count(Child::serial) = Sum(Child::yescalc).

Define a field using the Min function for the child table and place the field on the parent layout (so the result will be for each parent). With "no" = 0 and "yes" = 1, if you have any child with "no", the result will be 0, otherwise 1.

Perfect, thanks! I knew there had to be a way to do it.

Transpower's suggestion will probably be faster to calculate. Case( Min(Child::yescalc), "yes", "no" )
