What I want to accomplish seems very simple, but I can't get figure it out. I have 2 columns in my table that I want to manipulate:ActualHoursEstimatedHoursI want to create a third column in the same table called PercentComplete, which is computed by ActualHours / EstimatedHours.I've only seem examples that create new tables. I haven't seen anything that allows me to compute values based on information in the same table.I know this seems so simple, and the solution probably is, but unfortunately I'm stumped. Any help would be greatly appreciated.Thanks!
