Hello, I have been getting suggestions for the past few days about how to fix some mistakes in my report. I now, have 2 (Invoice and Payment) subreports in my major report. I am now trying to calculate fields from the 2 subreports to show in the project footer of my major report. I think that I have my calculated fields up & running in my report. The only problem is that if there is no payment or no invoice, the calculated amount shows an error for some projects. How can I fix this problem?
