JavaScript Error?? Cookie Monster

[gidgetthekid]

I'm trying to sell a Cookie Monster item, but keep getting the message:

It looks like there's a problem with this listing.

    "Item description - Your listing cannot contain javascript (".cookie", "cookie(", "replace(", IFRAME, META, or includes), cookies or base href." 

I know nothing about javascript and have no idea why I'm getting this message. I did a cut and paste from a Word document as I normally do.
