Validation w3C

Bonjour, je voudrais valider mon code en w3C, mais il y a certaine erreur que je ne comprend pas malgré mes recherche sur googles comme:

# Warning Line 174, Column 48: cannot generate system identifier for general entity "prix"

window.location='./index.php?prod='+produit+'&prix='+prix+'&marque='+marque

✉

An entity reference was found in the document, but there is no reference by that name defined. Often this is caused by misspelling the reference name, unencoded ampersands, or by leaving off the trailing semicolon (;). The most common cause of this error is unencoded ampersands in URLs as described by the WDG in "Ampersands in URLs".

Entity references start with an ampersand (&) and end with a semicolon (;). If you want to use a literal ampersand in your document you must encode it as "&" (even inside URLs!). Be careful to end entity references with a semicolon or your entity reference may get interpreted in connection with the following text. Also keep in mind that named entity references are case-sensitive; &Aelig; and æ are different characters.

If this error appears in some markup generated by PHP's session handling code, this article has explanations and solutions to your problem.

Note that in most documents, errors related to entity references will trigger up to 5 separate messages from the Validator. Usually these will all disappear when the original problem is fixed.


ou alors celle ci:
Line 174, Column 52: reference not terminated by REFC delimiter

window.location='./index.php?prod='+produit+'&prix='+prix+'&marque='+marque

✉

If you meant to include an entity that starts with "&", then you should terminate it with ";". Another reason for this error message is that you inadvertently created an entity by failing to escape an "&" character just before this text.


voici la fonction ou il y a le probleme

# function changementProduit(time)
# {
# //on recharge la page en passe le groupe par la méthode GET
#
# produit=document.forms["formproduit"].elements["produitname"].value;
# prix=document.forms["formprix"].elements["nameprix"].value;
# marque=document.forms["formmarque"].elements["namemarque"].value;
# window.location='./index.php?prod='+produit+'&prix='+prix+'&marque='+marque
# }

merci de votre aide
