I wish I could select the area of risk from NSCombobox "A" and then automatically its "fee" should appear in cell "B". This is because I'll have to multiply the "Surface" and "rate".
Column "A" binding: Value bind to: Particelle controller key: arrangedObjects model key path: nome.
NSCombobox binding: Content bind to: Area Rischio controller key: arrangedObjects
Content Values
bind to: arrangedObjects
model key path: nome
With this set up the combobox shows me are the area of risk included and once selected the area of risk desired recording. Now I would like once you have selected the area of risk appeared the fee in the field beside it.
