Column calculation

Column calculation


Hi, I need your help for making a new column basing on the following information:


I need to calculate for each NIVEL DE COMPLEJIDAD the percentange that the VALOR GLOSA INICIAL represents from the TOTAL VALOR DE FACTURACIÓN:




So the new column must do something like this:

NIVEL DE COMPLEJIDAD            NEW COLUMN
I                                                  (1.395.400/4.584.843.286)*100
II                                                 (39.989.637/4.584.843.286)*100
III                                                (95.496.254/4.584.843.286)*100
IV                                               (2.034.223/4.584.843.286)*100

I really appreciate you help.

Thank you
