function surveyValidateQuestion(survey, options) {
    //options.data contains the data for the current page.
    var countryName = options.data["country"];
    //If the question is empty then do nothing
    if (!countryName) {
        options.complete();
        return;

    //call the ajax method
    $.ajax({

        var found = false;
        var countries = data;
        for (var i = 0; i < countries.length; i++) {
            if (countries[i].name == countryName) {
                found = true; break;
            }
