Sorry Folks there is a slight bug in the spreadsheet!
The data range for the scattergram MUST be altered to fit the number of data
sets entered in the spreadsheet, at present it is set to include some cells
with text contents which upsets the plotting.
Also, if you want to calculate Cubital Indices only, then a value will have
to be entered in column B of the data set.
Sorry for any inconvenience
