this code give error.....how solve it?

check yammer documentation on https://developer.yammer.com/yammer-sdks/#javascript-sdk may need register app, use updated js sdk call page - you'll need newer api call

<script type="text/javascript" data-app-id="[your app id]" src="https://assets.yammer.com/assets/platform_js_sdk.js"></script> 

then in group call just

yam.platform.request({ 

url: "messages/in_group/1312007.json?threaded=true"

hope helps. rich
