Unable to submit form after one click on submit button

Subject: Unable to submit form after one click on submit button

Description: The user has to click on Submit Button 3 times after updating the details to submit the form. If the Submit button is clicked once or twice, the form doesn't get submitted.

We have found its happening due to 2 on submit catalog client script.. Could you please here me here to find out what's going wrong exactly in script

Script 1 - If the user is from new zeland showing  errors message to check the required checkboxes

function onSubmit() {

    //  Making the checkboxes mandatory for New Zealand users

    if (g_scratchpad.isFormValid)

        return true;

    var gdjUser = new GlideAjax('global.KHCatalogAjaxUtilsNewHire');

    gdjUser.addParam('sysparm_name', 'checkNZUser');

    gdjUser.addParam('sysparm_hrUser', g_user.userID);

    gdjUser.getXMLAnswer(setAnswer);

    return false;

    function setAnswer(answer) {

         if (answer == 'false') {

           g_scratchpad.isFormValid = true;

        } else {

            var a = g_form.getBooleanValue('employment_contract_signed_by_employee');

            var b = g_form.getBooleanValue('personal_details_form');

            var c = g_form.getBooleanValue('tax_details_form');

            if (a == false || b == false || c == false) {

           g_form.addErrorMessage("Please check the checkbox for Employment contract signed by employee, Personal details and Tax details");

                return false;

            }

            // var actionName = g_form.getActionName();

            g_scratchpad.isFormValid = true;

            g_form.submit();

        }

    }

}

Script 2 - If the user is from Australia showing  errors message to check the required checkboxes

function onSubmit() {

   //  Making the checkboxes mandatory for Australia users

    if (g_scratchpad.isFormsValid)

        return true;

    var AU = new GlideAjax('global.KHCatalogAjaxUtilsNewHire');

    AU.addParam('sysparm_name', 'checkAUUser');

    AU.addParam('sysparm_hrUser', g_user.userID);

    AU.getXMLAnswer(setAns);

    return false;

    function setAns(answer) {

        if (answer == 'false') {

              g_scratchpad.isFormsValid = true;

        } else {

         var a = g_form.getBooleanValue('employment_contract_signed_by_employ');

            var b = g_form.getBooleanValue('personal_details_for');

            var c = g_form.getBooleanValue('tax_file_declaration');

            var d = g_form.getBooleanValue('super_form_smsf_attach_compliance_letter');

           if (a == false || b == false || c == false || d == false) {

              g_form.addErrorMessage("Please check the checkbox for Employment contract signed by employee, Personal details, Tax details and Super Form");

                return false;

            }

          //  var actionName = g_form.getActionName();

            g_scratchpad.isFormsValid = true;

            g_form.submit();

        }

    }

}
