Subtracting Matrix Table Columns and Creating a new Matrix Table

Hi _AAndrade I place the Term Ordinal as my columns and I was able to slice the data and see it by term. However, another request that is being very tricky is to place the result under previous term. In another words: If Fall 2021 has 6 actives and Summer 2021 has 8 actives the result of -2 should be placed under Summer 2021 I tried to change the attrition formula but not having any luck to get this last piece working. Would you please help or guide me? I certainly appreciate your help and time and your solution has been the best so far and I am so grateful you took the time and looked into this solution. Looking forward to hearing from you.
