i have 3 text input fields in my html form. they are named as:
amount, paid & change
the amount field is automatically field in and has a value already, which is a numerical value.
in the paid field i will input how much is paid, then i need a script that will subtract the amount from the paid field and tell me how much change is due in the change field.
can anyone please tell me how i can achieve this.
thank you
