Solved. I need the Proxy. It works now.

Thanks for your help.

Have you seen this error before ? If so, what is the problem and how do you fix it ?

Thanks,
Mike

XMLHttpRequest cannot load http://api2.yp.com/listings/v1/search.... No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://appery.io' is therefore not allowed access.

Is that in the Test tab ?

If so, I don't see any errors.

Did I supply you enough information ?

Here is the preview screen of the app
I fill in "Pizza in Chicago" and click the Find button,
It shows a circle w/arrrow moving briefly and then it quits. It doesn't show any results.
