Wow! Strange error! There's not even an $ sign in that line.. just template code.
Are you sure you edited all the necessary files and upload them properly?
btw, strange nickname. Are you by any change Portuguese? =)
Admincp -> Styles and Templates -> Style manager -> your_style(s) -> Edit templates -> Navigation / Breadcrumb group -> navbar [edit]
If the navbar isn't there, expand all groups clicking in the first [« »] sign and search the page for navbar
