I seem to be the only one having difficulty with this portion of the Challenge 2.  In the video it asks that in the Account Object, if Type "Customer-Direct", or  "Customer-Channel", are selected that the "Account Name" can NOT be changed.  Below is the error message I received and the formula I used to try and complete the task.  I thought this was pretty straightforward, but I'm obviously missing something.  Any help is greatly appreciated!

Error Message:
Challenge Not yet complete... here's what's wrong:
A validation rule did not prevent an Account's name from being changed when Type is 'Customer - Direct'.
