Comment afficher page vide si fichier introuvable

bonjour à tous,

je travaille avec la macro ci-dessous qui importe cinq(5) fichiers,chaque partie de la macro s'occupe d'un fichier,elle le retrouve par son chemin .

Le probleme qui se pose c'est qu'elle bug si elle ne trouve pas un de ces 5 fichiers ;tandis que je voudrais qu'elle affiche une page vide dans le cas ou le fichier est introuvable,puis passer au fichier suivant.

Merci d'avance pour ceux qui voudrons m'aider.
