Validation du code js

Bonjour
lorsque je fais la validation HTML 4.01 Transitional du site il me sort des erreurs comme ci-dessou

Code:

---

1 2 3 4 5 6 7 8 9 10

Error Line 104 column 92: end tag for element "MARQUEE" which is not open. ...:1px solid #9F5A8D">'+text+'</marquee>' The Validator found an end tag for the above element, but that element is not currently open. This is often caused by a leftover end tag from an element that was removed during editing, or by an implicitly closed element (if you have an error related to an element being used where it is not allowed, this is almost certainly the case). In the latter case this error will disappear as soon as you fix the original problem.   If this error occured in a script section of your document, you should probably read this FAQ entry.   ✉   Error Line 111 column 63: end tag for element "B" which is not open. ...tooltip2.document.nstip.document.write('<b>'+text+'</b>')

comme vous pouvez le voir ce n'est pas une erreur d'ouvertire de balise car
pour l'exemple juste au dessus la balise <b> est bien ouverte

comment faire pour que ces erreurs de validation ne s'affiche plus?

merci de votre aide

enlever la balise marquee ?:aie:

essaye de mettre le style dans le head

Code:

---

1 2 3 4

<style type='text/css'> marquee {...} </style>

---

mais à mon avis c'est plus une question de balise non valides
