Using In Column Data to Calculate a New Column
I am trying to use the data in columns to calculate in a new column.The columns with data will be ID, From(Depth),and RLThe problem is I want to calculate a "depth" below a specific point (RL).How I see the formula is if ID=ID and From = 0 then use the RL at From=0 and subtract the RL at the next From and repeat till the a new ID
