Insertion DHTML dans page modèle .dwt Dreamweaver

Bonjour,
Suite de mes aventures...
J'ai abandonné la piste Flash pour créer mon menu ; je l'ai fait en DHTML. Voici le code :

<script type="text/javascript" language="JavaScript1.2">

Il fonctionne bien quand je l'insère dans une page html ; le test F12 marche bien. Or ce que je voudrais c'est le mettre dans mes pages Modèles (.dwt) déjà créées avec Dreamweaver, pour éviter de le mettre sur chacune des pages générées. Et là, plus rien, ça ne marche plus ! Une idée ?
Merci d'avance.
