validare plimun nivo slider

[MiRo' Art Design]

ciao a tutti
ho un picolo problemino con plimun nivo slider, quando vado a validare il codice mi da 5 errori
che non so proprio dove correggerli. è sicuramente lo slider perchè prima non ho niente appena lo attivo me li da.
Qualcuno si è imbattuto in questo problema? Ha risolto?
Grazie in anticipo
gli errori sono di questo tipo:

• Line 204, Column 30: required attribute "type" not specified

  <script language="JavaScript">

    ✉
     The attribute given above is required for an element that you've used, but you have omitted it. For instance, in most HTML and XHTML document types the "type" attribute is required on the "script" element and the "alt" attribute is required for the "img" element.
   Typical values for type are type="text/css" for <style> and type="text/javascript" for <script>.
   
• Line 207, Column 166: character "<" is the first character of a delimiter but occurred as data

  …','778787','949990793917947998942577939317'),l=x.length;while(++a<=l){m=x[l-a];

     This message may appear in several cases:
   
  • You tried to include the "<" character in your page: you should escape it as "&lt;"
  • You used an unescaped ampersand "&": this may be valid in some contexts, but it is recommended to use "&amp;", which is always safe.
  • Another possibility is that you forgot to close quotes in a previous tag.
   
• Line 209, Column 19: character ";" not allowed in attribute specification list

  for(v=0;v<m.length;){t+=m.charAt(v++);

    ✉
• Line 209, Column 19: element "m.length" undefined

  for(v=0;v<m.length;){t+=m.charAt(v++);

     You have used the element named above in your document, but the document type you are using does not define an element of that name. This error is often caused by:
   
  • incorrect use of the "Strict" document type with a document that uses frames (e.g. you must use the "Frameset" document type to get the "<frameset>" element),
  • by using vendor proprietary extensions such as "<spacer>" or "<marquee>" (this is usually fixed by using CSS to achieve the desired effect instead).
  • by using upper-case tags in XHTML (in XHTML attributes and elements must be all lower-case).
   
• Line 211, Column 34: character "<" is the first character of a delimiter but occurred as data

  t='';}}x[l-a]=z;}document.write('<'+x[0]+' '+x[4]+'>.'+x[2]+'{'+x[1]+'}</'+x[0]…
