I need to have a field display the results of 4 other fields in a form.
To explain - One field will have a value of 250.00, next field 100.00, next field will be entered by the user, next field 50.00
So the calculation I need displayed is (250+100+(number entered by user * 50)).
Any help would be greatly appreciated.
Thanks,
Andy.
