I get this error on the "Add a form to the Visual Force Page.

Step Not yet complete... here's what's wrong:
The 'ContactForm' Visualforce page does not have a apex:inputField component
Note: you may run into errors if you've skipped previous steps.

However the Apex:inputField comonent is there.  Here is my code snipet.

<apex:form>
    Hello <apex:inputField value="
{!Contact.FirstName}" />
    <br /><apex:commandButton value="Submit" action="
{!save}"/>
</apex:form>
