I tried to do an if/then statement in javascript but the then command is being ignored. Any ideas on why?

Specifically I want the form to be validated that the two text boxes are not blank and once that is validated I want a DIV ID = section2 to appear.

function checkanswers() {

    var fdet = document.wastheform;



    if (fdet.question_type[0].checked) {

        var elements = new Array(name,address);

        var elements_name = new Array(name, address);

        for (var i = 0; i < elements.length; i++) {

            if ($(# + elements[i]).val() == ) {

                err = Please enter  + elements_name[i] + ;

                alert(err);

                return false;

            }

        }

        $(#section2).show();

    }
