button won't accept url

This is for the call to action button 2. No matter what URL I place in the URL field, nothing happens. I have typed it in directly and linked to it. I just get “undefined” and when I placed the url in the classic mode, it looked like this, but still doesn’t link to page:
[/callout][spacer height=”150″][vc_cta_button2 0=”link=<span” 1=”tabindex=-1>http://www.grocerykartbythebay.net/?page_id=3693” h2=”Ways to Contact Me” style=”round” txt_align=”center” title=”Contact” btn_style=”rounded” color=”juicy_pink” size=”md” position=”right” accent_color=”#0d5263″ id=”sample-permalink” link=”||”]

thank you
