Hello
I am experiencing a deep difficulty trying to build the grey curve, when I copy/paste the data I get from the calibration of my test-strip printed (PT/PD) and scanned. I had to use the "DATA TOOL" and its smoothing tool to get the numbers in order, and it was ok.
The problem occurs when I paste them in the excel sheet: the result I get is this:
#VALUE, without any information. Can someone help me?
Thank you!!
Maria
