Hi!
I have a workbook (workbook1). In this workbook I perform a couple of calculations, among others, a couple of SUMIFS witch retrives data from another workbook (workbook 2). So far, so good. When I open workbook 1, and choose to update or choosing another intervall of dates, I get #VALUE!. The only way to get everything to work, is to keep all workbooks open...and that is really not an option. Suggestions?
