Challenge Not yet complete... here's what's wrong: 
There was an unexpected error in your org which is preventing this assessment check from completing: System.DmlException: Process failed. First exception on row 0; first error: NO_APPLICABLE_PROCESS, No applicable approval process was found.: []

Help Needed.

Challenge Not yet complete... here's what's wrong: 
The 'Google Info' custom button was not found. Make sure that it is a Detail Page Button (not link) and that its added to the page layout. If you are still having problems, ensure that you are NOT using Record types for the Contact object. This challenge will not work with Record types so you will need to sign up for a new DE org and use that instead for this module.
