Help with Webcheck

[ringo42]

zabbix V2.2
I'm trying to get a status back from a webpage. If I paste this into a browser

http://user:[email protected]:8099/rest/healthcheck

then I get back

<response xmlns="http://rest-control-api.xsd" status="ok" code="200">
<version>3.3</version>
<op>GET:healthcheck</op>
<healthcheck>
<status>ok</status>
..........
so I want to check that status "ok"
I'm trying to set up a web scenario. I set the agent to chrome 17, and tried it with and without "http://user[email protected]:8099/rest/healthcheck" in the HTTP proxy box.
Under steps, I put in the URL http://user[email protected]:8099/rest/healthcheck
and in required strings, I put ok I also tried it without a required string.

what else do I need to do?
In lastest data I get
