My error is different than that though: Challenge Not yet complete... here's what's wrong: 
The process does not appear to be processing 'Closed Won' first and then 'Closed Won and Banking'.

Except for it does look to be in that correct order, and activated! I even went back and deleted the older Inactive versions to get the previous challange to pass. 

Here is a link to the challange: https://trailhead.salesforce.com/modules/workflow_migration/units/workflow_migration_order

Any suggesstions?

Hello All,
I am stuck in below trailhead chanllange. Please help me.

Using the Contact standard controller, create a Visualforce page which displays a Contact's First Name, Last Name and the Email address of the Contact's Owner.The page must be named 'ContactView'.
It must reference the Contact standard controller.
It should include a bound variable that uses the standard controller to display the first name of the Contact.
It should include a bound variable that uses the standard controller to display the last name of the Contact.
It should include a bound variable that uses the standard controller to display the Contact Owner's email.

I am getting below error..
Challenge not yet complete... here's what's wrong:
The page does not include a bound first name variable for the Contact record
Please refer below screenshot for vf code.

I have this very simple class..  

trigger RestrictContactByName on Contact (before insert, before update) {
    //check contacts prior to insert or update for invalid data
    For (Contact c : Trigger.New) {
        if(c.LastName == 'INVALIDNAME') {   //invalidname is invalid
            c.AddError('The Last Name "'+c.LastName+'" is not allowed for DML');
        }
    }
}

.. and the corresponding Test Class:  

@isTest
private class TestRestrictContactByName {

	@isTest static void metodoTest() {
		
		List listaContatti = new List();
		Contact c1 = new Contact(FirstName='Francesco', LastName='Riggio');
		Contact c2 = new Contact(LastName = 'INVALIDNAME');
		listaContatti.add(c1);
		listaContatti.add(c2);
		
		//insert listaContatti;
		
		// Perform test
        Test.startTest();
        Database.SaveResult [] result = Database.insert(listaContatti, false);
        Test.stopTest(); 
		
		c1.LastName = 'INVALIDNAME';
		update c1;
       		
	}
	
}

When I run the Test class from the Developer Console I get 100% of coverage on the RestrictContactByName class but, when I check the challenge on the trailhead it returns the error:

Challenge not yet complete... here's what's wrong: The 'RestrictContactByName' class did not achieve 100% code coverage via your test methods

Has someone had my same issue?
