I am creating a map to record data and locations of chemical spraying for noxious weeds throughout a county. Obviously the type and amount of chemical needs to be recorded each day. I am trying to figure out the simplest way to record this as there is a possibility of using multiple chemicals in a tank. I understand how to create lists for a field, but I am wondering if its possible to create more than one list or have multiple choices for a specific field? Example: I am using Round-Up (out of 4 choices of chemicals) and put 10 oz. in a specific tank. My field could be labeled "Chemicals" and the list associated with it could be the list of chemicals, but how could I enter in the amount as well? Sorry for any confusion...thanks for the help.
