I 'm in the process of beginning this superbadge and all my videos say "Access Denied This player has restricted access"   I've not had probelems on watching other videos.

Do I need to adjust something?   Thanks.

Has anyone encountered this issue?

I have tried clearing my cache, using Chrome, IE, Firefox, I don't know what else to try.

Salesforce support tells me to go to trailhead and click on a link (Login issue) but even when I navigate to that page, it re-loads and gives me the same error.

 

This page isn’t workingtrailhead.salesforce.com is currently unable to handle this request.
HTTP ERROR 500

 

Every trailhead page I navigate to gives me this error.

Your company sells cylindrical hyperbaric chambers. You need a formula field that calculates the volume of a cylinder for you, rounded to the nearest whole number, given its radius and height. Use the existing mathematical formula for the volume of a cylinder, V = πr2h, where r is the radius of the cylinder, h is the height, and π is the constant Pi. Note: Although this formula field might best be created on a custom object, for simplicity, we’ll create this formula on the Opportunity object.
>Create 2 custom fields of type Number on the Opportunity object: ‘radius’ with a resulting API name of ‘radius__c’ and ‘height’ with a resulting API name of ‘height__c’.
>The formula should be named ‘Cylinder Volume’, with the resulting API name ‘Cylinder_Volume__c‘ and should be created on the Opportunity object.
>The formula should reference the custom fields ‘radius__c‘ and ‘height__c‘.
>The formula should use 3.14159 as an approximation of Pi.

Heres the challenge that im stuck on. i have created the 2 custom fields. What im stuck on is where do we create the formula. Do we put it in the custom fields or is there another place u insert it?

thanks if anyone can help
