Hello,
Thank you for pointing out that problem with the Excel workbook. We will fix that in the next update.
In the meantime, you can fix your copy of SAM by editing the workbook in the SAM installation folder. The em>single_owner.xlsx[/i] file is in the folder C:\SAM\2017.1.17\runtime\spreadsheets.
When you click the Send to Excel with Equations button on the Cash Flow tab of the Results page, SAM opens a copy of that Excel file, and populates the input cells with values from SAM's input pages. You can modify the Excel file to make changes to or correct calculations. If you do that, be careful to close SAM while you edit the Excel file, and to close Excel before you start SAM. You may want to make a backup copy of the workbook before you make any changes.
Best regards,
Paul.
