I'm trying to create a new playground, but am unable to do so.  When I try to select create new trailhead playground, nothing happens.  The list doesn't even register that my curser is hovering over the options in the list.  What am I doing wrong?

The following won't validate, but won't pass the validation in this trail.  Quantity field is howver using the correct field.  Thoughts?



<aura:component>

<aura:attribute name="item" type="Camping_Item__c" required="true"/>    
    <ui:outputText value="{!v.item.Name}"/>
    <ui:outputCheckbox value="{!v.item.Packed__c}"/>
    <ui:outputCurrency value="{!v.item.Price__c}"/>
      <ui:outputNumber value="{!v.item.Quantity}"/>
            
</aura:component>

Trailhead seems to not be working well today.  It isn't recording my completed challenges and now is saying that I need to log in, but then won't let me do so.  Any idea?
