ETC relative brightness calculator

Good afternoon,

For a small theatre we have about 20 PC's, the performer 2500 q6
As expected with the etc nomad as color picker some adjustment to the color calibration is needed.
I have rented a spectrometer c-800 if im correct and this week i will start with the measurements.

However when i test the excel sheet (version 1.4) and fill in some (in my opinion good) test results, the relative brightness column gives an #NAME? error and no values are displayed.

Does anyone see/know what i'm doing wrong?

If needed I can provide extra information
