I have read all the posts about formcalc, etc and have no clue what is going on. All I need to do is have Livecycle automatically sum the total of two simple number fields into a third. Number of students and number of adults for into a total field. I am not a code writer, and am really new this. Thanks for your help in advance.
Suppose you have three numeric fields with name NumericField1, NumericField2 and NumericField3.
If you need to simply want to set answer of NumericField1 + NumericField2 into NumericField3, then;
1. Click to select NumericField3
2. Menubar Window -> Script Editor
3. Change "Show" menu in script editor to "calculate"
4. Confirm "Language" menu in script editor is "FormCalc"
5. Input script like below
$.rawValue = NumericField1.rawValue + NumericField2.rawValue
