Uexpected token 'tag' jade node.js

I get:

    Unexpected token 'tag' expected 'text', 'code', ':', 'newline' or 'eos'

because of this code:

        label(for="polaziste")Polaziste

in

#main
    form(action="/raspored" method=post)
        label(for="polaziste")Polaziste
        input(type="list" id="polaziste")
        datalist#polaziste
            for pol,i in popis
                option(value = pol)

Why? :)
