Hi @Anonymous ，

I have no access to your shared file, could you please refer the following thread to re-share the file with me? Thank you. What is the end result you want? Are you trying to understand the meaning or function of the formulas in the two screenshots above? Or are you saying that these two formulas do not return the correct results?
