It was recently reported to me that the cubic spline spreadsheet CSpline2.xls (posted here) was crashing on loading in Excel 2003. It seems that the problem was with the ChartSpline function, and that there are no problems if this function is removed. I haven’t tracked down exactly what causes the crash, but until I do I have saved two versions of the file:
- CSpline2.xlsb includes the ChartSpline function for use in Excel 2007 and 2010
- CSpline2.xls has the ChartSpline function deleted
The new files can be downloaded from CSpline2.zip
Please let me know if there are any remaining problems.
