Input fields that relate to a scoring system?

Is it possible (I'm sure it is!) to have a system whereby if you alter the first field, the value in there affects the second field? For example:

Position [  ]  Points [  ]
Position [  ]  Points [  ]
Position [  ]  Points [  ]

You have 10 or so of these fields and each relate to each other. If you enter 1 in to position, the points field should pre-populate with 20 points, if you enter 2 then it pre-populates with the related value, then to relate this to all of the rows?

Maybe this will get you moving in the right direction:

$('#position1').change(function() {
    if($(this).val() == '1') {
        $('#points1').val('20');
    }
});

the logic can just get more complex if you want to relate more fields to the value of that one. Hopefully this helps.

Here's a simple example

Here is a JS Fiddle, I'm using the change event in jquery on the first input to run an if statement to place a value in the second input. 

$('document').ready(function(){
    $('#position').change(function(){
       if($('#position').val()=="1"){$('#points').val("20");}
    });
});
