I have done this many times before but now i seem to have a simple expression even work. I have created a new form that i can input tax data into a table. I have put text fileds next to the input fields to total the columns i with to in the table. I used Sum(Fuel Costs) with should work but in normal view on the form the field looks like #name. There are attachments of the table, the form nomal view and design view. I dont know what im doing wrong?
