$('#preview').bind('click', function(e) {
    var minimum     = parseInt($('#minimum').val());
    var maximum     = parseInt($('#maximum').val());
    var interval    = parseInt($('#interval').val());

    var times   = Math.floor(maximum/interval);
    var html    = '';

    for (var i = 0; i < times; i++) {
        html += "<option value='" + minimum.toFixed(2) + "'>" + minimum.toFixed(2) + "</option>";
        minimum += interval;
        if (minimum > maximum) {
            break;
        };
