Hello, I am new to Caspio, I encounter a problem here. I have two Tables Table#1: Investment(Investment_ID, Client_ID, Latest Transaction date, BookValue, MarketValue) e.g. Invest001|Nov 1, 2018|500|1000 Invest001|July 1, 2018|800|2000 Table#2: Investment Transaction(Investment_ID, BookValue, MarketValue, Transaction_Date) e.g in Table #1 I have following records, Invest001|100|100|Oct 1, 2018 Invest002|800|2000|July 1, 2018 Invest001|100|200|Oct 10, 2018 Invest001|100|300|Oct 15, 2018 Invest001|200|500| Sep 1, 2018 Invest001|500|1000|Nov 1, 2018 Here I would like to make the following action execute whenever I update the table. Latest Transaction Date = Table#2:Latest Investment Transaction：Transaction_Date BookValue = Table#2:Latest Investment Transaction: BookValue MarketValue = Table#2:Latest Investment Transaction: MarketValue What can I do to make this happen? Any help will be appreciated, Thank you very much in advance,
