Calculating a Product Field « Gravity Support Forums

I'm creating a form for a product. When the user selects the county the live in, I want to populate 2 separate product fields, with the cost associated with their county. I know that I can use a product drop down and use the total cost associated with their county, but the customer would like the 2 costs listed separately.

i.e - User chooses Orange County
Exam fee = $40
Travel fee = $100

Can this be done with a calculated product field? Or do I need to create a function and use a hook with the onchange event (if this can be done, please point me to an example)

I've been trying to find an answer to this for a full day. I tried the following in an html field on the form: I've tried having the input listed as #input_30 and #input_3_30. I haven't worked on actually changing the field values yet, but I just wanted to see if I could get the onchange event to trigger a function. Anyone successfully do this?
```
<script type="text/javascript">
jQuery(document).ready(	function() {
		$('#input_3_30').bind('onchange', function (){
			CalculateFees(this.form);
	  });
});

function CalculateFees(frm) {
        alert('here');

}</script>
```

You could simply just use conditional logic to show/hide individual product fields based on county selection.
