I don't know what your trying but you CAN store the individual visit
number. This is a NORMAL number field (NOT A CALC) which just happens
to have an auto enter value on it.

If your trying to store the total number of visits, it can also be done
but that means you have to script it, every time a new visit is created
set a field in person to the count of visits. From the Visit table you
can reference that field as a related field.

I got it to work...I had to make sure that it was always validating the
field but and I did a
This visit number = Count(PersonCount ::PersonID) + 1 or that could
also be the TotalVisits +1

Thanks so much for your help...
