I am trying to create a table that sums two other fields into a third. I am not sure if this can be done without a query...but if it can, does anyone know how? I am currently trying to place the expression within the defaut value such as =[IntShares] + [curPrice per Share]. Everytime I try to go back to the table it says ut doesnt recognize IntShares as a field or something. Anyway, am I barking up the wrong tree here? Thank you!! for any help.
