Greetings,
Am working on petrol station management system, and for the same thing I need to compute fields for calculating prices and meters etc, but I do not know the code to make it work, can anyone tell me the same in details ?
There are 2 fields which need to be computed one for subtraction and another for multiplication, I need to write the code in compute field which is present in the field making form (front end)
for subtract :
field name : close_meter_reading - open_meter_reading = difference
for multiply :
field name : ltr * unit_price = total_price
