There is a bug in the most recent excel that is disabling the spline curve functions in the Piezography Curve Adjustment workbook.
I’m debugging but this may take some time for Microsoft (and myself) to fix.

I re-worked the visual basic code on this tool. Test this on the most recent version of Excel if you have accidentally installed it.
Ok. From other posts. This seems to be working.
I will get this into the next version of PiezoDN.
