I'm on the Display Records, Fields, and Tables module under Visualforce Basics, and I'm unable to complete the challenge

Here is the criteria:
Create a page which displays a subset of Opportunity fields using apex:outputField components. Bind the Name, Amount, Close Date and Account Name fields to the apex:outputField components.
Challenge Requirements
The page must be named OppView
It must reference the Opportunity standard controller
It must have four apex:outputField components bound to the following Opportunity fields:
Opportunity Name
Amount
Close Date
Account Name of the Opportunity

Here is my code from the dev console:
<apex:page standardController="Opportunity">
    <apex:pageBlock title="Opportunities">
        <apex:pageBlockSection>
            <apex:outputField value="{!Opportunity.Name}"/>
            <apex:outputField value="{!Opportunity.Amount}"/>
            <apex:outputField value="{!Opportunity.CloseDate}"/>
            <apex:outputField value="{!Opportunity.AccountId}"/>
        </apex:pageBlockSection>
    </apex:pageBlock>
</apex:page>


Here's the error I receive:
The page does not include a apex:outputField component bound to the opportunity amount

Also here's the error I receive from the dev console, it is having trouble running the outputField line for the Opportunity.Amount:
Currency fields on entities with effective dated currency are not supported.

I'm not sure if it's a configuration or dev issue, but any assistance to clear this challenge would be greatly appreciated!
