I have a dropdown list on a form that lists different types of credit cards. I also have a form field that is called charge card fee and I would like this to be populated with a $ amount based on what card was selected from the dropdown. Each card has a different fee that is a % of the sale price. So there is a third field of Price that is involved.
Is there a way to have the fee field calculated and populated using javascript?

Any help is appreciated. Thanks.
