javascript code for delivery charge

If user inputs distance is within 3 miles, there's no charge.
If user lives more than 3 miles but not more than 12 they pay.
No delivery over 12 miles.

I'm struggling with making the code do more than 3 but less than 12 miles.
Could anyone give me a bit of a clue please?
Below is the partially coded page.
<SCRIPT LANGUAGE = "JavaScript"> // A delivery charge program for the Company var distance;
var extraDistance; // A variable you will need to use
distance = window.prompt('Please enter the distance in miles', ''); distance = parseFloat(distance); // Insert your code here </SCRIPT>

Moved to Javascript forum for better response.
Code:
if( valueEnter > 3 && valueEnter < 12 )
{
    Do something
}
