Solidworks VBA пропустить пустой массив

Я создаю макрос для рендеринга моделей SolidWorks. Он предназначен для отображения всех конфигураций в сборке. Часть кода, над которой я работаю, должна извлекать массу всех конфигураций и помещать ее в конец имени рендеринга. Для большинства конфигураций это работает.

Только те, где в сборке нет моделей, то есть нет данных, доступных в массовых свойствах, выдавали бы мне ошибку: Несоответствие типов. Код выглядит так (место ошибки выделено **):

Поэтому мне интересно, есть ли возможность пропустить извлечение свойств для конфигураций с ошибками (и, если возможно, заменить его на «0» в имени рендеринга).

Надеюсь, вы можете мне помочь. Заранее спасибо!
