    Resolving partial sums - For loop?

      Hi all,

       

      I have an interesting issue I am about to take on. I need to calculate a partial sum.

       

      Y = T - aΣ x/(1+b)^i


      Where the partial sum (Σ) is from i=1 to n and varies for each record between 1 and 25. Basically all of the terms of the equation are known and are in a single row of a table except for y. Each record has this single row of known terms.


      I would like to add a column to the table for y using the data from that single row into this equation.


      How do I get this partial sum to resolve? Is a For loop in the script my best option?

       

      Many thanks,

       

      Mike
