In table #1, I need to create a field that calculates a SUM(values) rollup of the costs associated to records in another table (let’s call it table #2). I created a linked field that links table #1 to table #2, but is there a way to link to all the records in table #2? Let’s say the records in table #2 are labeled “A” “B” “C” etc… I would like a field in table #1 to link to all the records in table #2 that are labeled “A.” But there could be hundreds of them theoretically, so manually linking them isn’t feasible. I’ve tried copying the values into the linked field, but it only returns one link in each field instead of all the records that match. So instead of summing the values in all the records labeled A in table #2, I just get one of the costs in table #2. Sorry if that description isn’t clear! This seems a bit complicated to describe! I’m essentially trying to replicate the function of a Match/Index/Sum formula in Airtable!
