Well, I've given you to start with... why not try and learn?

Thanks. I don't know how to write javascript.

You could... write it?

It's a simple Javascript function or three... all based around the onClick event. It would look something like this (this won't work, but will show you how to do it):

<select onChange='output()' id="whatever"><option name="1" value="1">1</option><option name="2" value="2">2</option></select>
<input type="text" id="cost" />

function output() {
  var x;
  x = document.getElementById('whatever').value;
  document.getElementById('cost').value = x;
  return;
}

See? Pretty simple. Now you just have to extrapolate that out to a working script, using some pretty basic "if" statements (or a switch, I guess, but I prefer "if")
