Instance Scan checks to find duplicate fields on same form.

[aditi__patil]

I am trying to write an instance scan check to find duplicate fields in same form. I am unable to get the findings for the given script for a table check : 

(function(finding, current) {

    var duplicatedViewElementAgg = new GlideAggregate('sys_ui_element');

    duplicatedViewElementAgg.addQuery('type', '');

    duplicatedViewElementAgg.addQuery('sys_ui_section.name', '!=', '');

    duplicatedViewElementAgg.groupBy('element');

    duplicatedViewElementAgg.groupBy('sys_ui_section.name');

    duplicatedViewElementAgg.groupBy('sys_ui_section.view');

    duplicatedViewElementAgg.addAggregate('COUNT');

    duplicatedViewElementAgg.addHaving('COUNT', '>', '1');

    duplicatedViewElementAgg.query();

    while (duplicatedViewElementAgg.next()) {

        var tableName = duplicatedViewElementAgg.getValue('sys_ui_section.name');

        var view = duplicatedViewElementAgg.getValue('sys_ui_section.view');

        var element = duplicatedViewElementAgg.getValue('element');

        checkFormsForView(view, tableName, element);

    }

    function checkFormsForView(view, tableName, element) {

        var formGR = new GlideRecord('sys_ui_form');

        formGR.addQuery('name', tableName);

        formGR.addQuery('view', view);

        formGR.addQuery('sys_user', '');

        formGR.query();

        while (formGR.next()) {

            var sectionIDs = getSectionIDs(formGR);

            var hasNoSections = sectionIDs.length == 0;

            if (hasNoSections) continue;

            var sectionNames = getSectionsNamesForElement(element, sectionIDs);

            var isInMultipleSections = sectionNames.length >= 2;

            if (isInMultipleSections) {

                finding.increment();

                finding.count = sectionNames.length;

                gs.print('DupField: ' + tableName + '.' + element + ', View: ' + view + ' (Sections: ' + sectionNames.join(', ') + ')');

            }

        }

    }

    function getSectionsNamesForElement(element, sectionIDs) {

        var sectionGR = new GlideRecord('sys_ui_element');

        sectionGR.addQuery('element', element);

        sectionGR.addQuery('sys_ui_section', 'IN', sectionIDs);

        sectionGR.query();

        var captions = [];

        while (sectionGR.next()) {

            var sectionCaption = sectionGR.sys_ui_section.getDisplayValue();

            if (sectionCaption == '') sectionCaption = 'DEFAULT';

            captions.push(sectionCaption);

        }

        return captions;

    }

    function getSectionIDs(formGR) {

        var sectionIDs = [];

        var formSectionGR = new GlideRecord('sys_ui_form_section');

        formSectionGR.addQuery('sys_ui_form', formGR.getUniqueValue());

        formSectionGR.query();

        while (formSectionGR.next()) {

            sectionIDs.push(formSectionGR.sys_ui_section + '');

        }

    }

})(finding, current);
