              console.log('values', values);
            }}
          >
            {({ submitForm }) => (
              <Form>
                <Field name="phone">
                  {({ field, meta }) => (
                    <FormItem
                      top="Телефон"
                      status={meta.touched && meta.error ? 'error' : 'default'}
                      bottom={meta.touched && meta.error ? meta.error : null}
                    >
                      <InputMask
