I need to know a little more about what you’re trying to track.
For instance, the easiest way to do what you describe would be to define three numeric fields, {CSA}
, {Restaurant}
, {Market}
, and a formula field, {Total}
, with the formula
SUM({CSA}, {Restaurant}, {Market})
Since you’re specifically asking about linking records, I assume that doesn’t suit your needs.
Ae you looking to have a table recording CSAs, with records of sale of each produce item to each, plus a table for restaurants and a table for farmers markets, and a way to total all sales for a produce type? Is the amount of produce harvested known up front, and you wish to reconcile that total against the amounts shipped, or do you arrive at the total only after summing shipments? Are you interested in knowing what produce went to which restaurant, or do you care only how much went to restaurants in general?
If you can let me know a bit more about your needs, I can better make recommendations.
