Hi,
See my sample project attached. There is an Excel file in the project where I have one tab that has daily stock volumes. In the other tab I calculate the prior 4 weeks total volume. In the sample app I add a new date to the Volumes tab of the Excel with some sample data and then run workbook.CalculateAllValue() and then save the excel workbook. However, when I open up the saved Excel file, in the Weekly Average tab the cells C3:E7 all say "#VALUE!". If I click into the cell and then click out of it the cells calculate correctly. Can you please help me identify the problem so that the correct calculated values show in those cells without having to click into them? I need to convert the file to PDF so I need the correct values to calculate without manual intervention.
Thanks so much,
Ben
