Can't Find This Validation Error

I'm getting this validation error from within<!--BOF footer menu display--> :

Line 663, Column 82: cannot generate system identifier for general entity "cPath"

…snob.authsafe.com/index.php?main_page=index&cPath=656">Women's Perfume</a></li>

I'm getting a few errors regarding this with the following explanations:

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

**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. **

Is this just a matter of making the ampersand look like &?

I've checked several folders and I can't find this although I do see it in View Source. Where would i make the correction(s)?

I see <!--BOF footer menu display--> in includes/templates/custom/common/tpl_footer.php but it doesn't contain the line with the error.

Thanks!

Any link generated via the zen_href_link() function will properly have the & symbol where it's needed.

So if the validator is pointing out that you've got links that use just & instead of & then those links are things you added yourself someplace. Go fix them.

Put the page(s) through http://validator.w3.org and check the box that says SHOW SOURCE. Then REVALIDATE and look at the revealed source (scroll down) to see where it is referenced. This will point to the area(s) that need attention.
