I have a table called "Opportunity" and a table called "Expenses", an Opportunity can have many Expenses. In the Opportunity table I have a field called "Current Year Fee". In the Expense table there is a field called "Amount". Since an Opportunity can have many Expenses and therefore many "Amounts", I am trying to create fields and or a report to calculate the difference or profit $ and % based on the "Current Year Fee" less all the expenses tied to that Opportunity. I am still pretty new to QuickBase so I would really appreciate any help and the more details the better. Thank you in advance!
