Trailhead course - Create a Role Hierarchy for a new Team Alignment - Getting error message even though it is created in playground

https://trailhead.salesforce.com/modules/data_security/units/data_security_roles

When I click on the "Check challenge" I'm getting the following error message:

---------------
Challenge Not yet complete... here's what's wrong: 
The Training Coordinator role does not exist or it does not report to the correct role.
---------------

My Trailhead Salesforce has been created properly,

https://cunning-goat-31466-dev-ed.lightning.force.com/one/one.app#/setup/Roles/home?a:t=1504713190100

To try to fix it, I deleted the roles I just created and re-added them again, but still getting this error message.

Please investigate and advise.
 

I'm having trouble validating challenge 2, with regard to Shinje Tashi's user settings.
ERROR: 
Challenge Not yet complete... here's what's wrong: 
Shinje Tashi does not have the user settings he needs.

The instructions say: "This sales data quality specialist supports the entire company and needs to be assigned a role that can see and access all account, contact, and opportunity records for the entire company. Use the Standard User profile."

First off, it seems odd not to handle this through a separate profile, but I'm trying to follow the directions. So...

I created Shinje as an active user, User License: Salesforce, Profile: Standard User. There isn't a role specified for him, and the instructions suggest providing access to all acct, contact and oppty records through a role assignment, so I created a Sales Data Admin role, reporting to the CEO. That role should provide RECORD access. Additionally, for OBJECT access, I created a permission set granting full access (CRED, View All, Modify All) to Acct, Contact, and Oppty objects and assigned it to Shinje. I created a separate permission set granting access to the Language preference field on Acct, named that permission set "Bilingual Pilot" as instructed, and assigned it to Shinje.

I'm not sure what I'm missing...

 

I've been working on this trail for a bit - and while I undertsand the concepts, I'm stumped on why I'm getting this error: 
 

Challenge Not yet complete... here's what's wrong: 
A Create a Record action for the Closed Won criteria node isn't properly configured. Make sure that it creates a draft contract according to the instructions in the ‘Create contract for closed opportunity’ task action. Make sure that Start Date is set by using a formula.

I've gone over all of the workflow tasks information to recreate the contact. If I activate the process and close an opportunity, it creates a contract with the expected information and the date is 1mo away with 12mo term. The workflow's task (which is the template for the actual contract) specifies the following: 
 

Use the closed opportunity to create a contract for the associated account. 

Account: The account associated with this opportunity
Status: Draft
Contract Start Date: 1 month from today
Contract Term: 12

Here are my actions: 


The Contract Start Date is set to the following formula:

DATE(
    YEAR(Today()) +
    FLOOR((1 + MONTH(Today())) / 12) -
    IF (MOD(MONTH(Today()) + 1, 12) = 0,
        1,
        0),

    MOD((1 + MONTH(Today()) - 1), 12) + 1,

    DAY(Today())
)

Again, for all practical purposes I'm passing this, as it functions and the contract is created. But I must be missing some small detail, named field, something that's tripping up the validation settings. Any help is appreciated!

 

Hi, 
 

I've re-stepped through the instructions multiple times, but can't seem to get the "online" button to show when my Live Agent console is online. For the last step to 'test your chat', my offline button does not change to online when I change my LiveAgent status to online. There's no error, but I'm not able to go through the rest of the module. Any suggestions of what could be wrong? 

Hello Ever one i want generate QR Code through apex And VF So can You plz give some code.


Thanks in Advance

Project custom object records should only be seen by the owner of the record and users above the owner on the role hierarchy. However, for some Project records, the Training Coordinator must also have Read Only visibility to the Project record.

Create a custom picklist field on the Project object called “Priority” with the following values: High, Medium, and Low. Then create a criteria-based Sharing Rule for Project records where the Priority = High to share those records with the Training Coordinator role.
