Error Corrector L* False #REF!

I have been attempting to make a new curve for Cansen BarytaP 2 and measuring two targets they are both exhibiting the same L* False column error #REF! (Reference dos not exist) on line 52 & 53. Line 54 shows a False error of at least -5.64. Changing those 3 lines I can get Line 54 to -0.02 but not 0. What is causing the same #REF! on two targets? ?

please share screenshots and a .zip of the measurement file

thanks,
Walker

Only two years later and I am trying again. I am now using a DTP70 where before I was using an EyeOne. I made a bunch of 51 step Colorport targets both Glossy and Matte for some new and old papers I have. Every one I scanned so far is having the same issue that I queried and then abandoned 2 years ago. They exhibit the same L* False column error #REF! (Reference dos not exist) on line 52 & 53. Line 54 shows a False error of at least -5.64. Changing those 3 lines I can get Line 54 to -0.02 but not 0. Attaching the Screenshot and the measurement file
