I have an excel 2003 workbook that is crashing in excel 2010. The workbook is crashing due to a reference to funcres created in vba. I do have the 'Analysis ToolPak' addin checked which is tied to funcres. Yet, I can't find funcres when I go to References under Tools when I'm in the Visual Basic editor. Is funcres automaticly loaded or referenced under 2010? How can I make the excel file function in both excel?
