I don't know what I'm doing wrong or if I'm having a total brain fart here (hey it is friday) but I'm trying to apply the round function to a field in one of my reports. So I go into the control source of the field and when I change it to Round ([SOURCE],0) it asks for a parameter, if I build it through the expression builder the field just reads #error. I've checked datatypes and made sure that the round function works in the same place with a number instead of the source so I know that thats not the problem. So how do you go about rounding this way?
