A semi-colon after a function declaration is an empty statement. The
getPrice function doesn't have a return statement, so its return value
will always be undefined (provided it executes without error).

Add a return statement to getPrice, maybe something like:
function getPrice(id) {
return $.get('db.xml', function(d){
...
});
}
