Good morning,
I am doing a stability study and want to set limits at +/- 20% of my result on day 1. I know how to add the limits to the graoh thanks to the help of another member of this community but now I would like to set up a formula so that this limit is calculated automatically taking into account the value on day 1 for each sample.
I wrote this formula for the upper bound but it doesn't work.
:Data[Row(), :Day == 1] * 1.2
I think I am wrong in using the index.
I attach the example table that I use with the results that I would like following the application of the formulas on the columns USL (value on Day 1 + 20%) and LSL (value on Day 1 - 20%) .
Does anyone have a solution?
Thanks in advance
