Google Maps Error: Invalid field Candidate__r for SObject Position__c

I'm working on the Force.com workbook and in the Visualforce section the suggested code is to pull in a map using Yahoo maps that doesn't seem to work. I found some code for Google Maps and am trying to pull the map from Google Map and display it in a section inside the Position object. Below are the objects and my code. Any help is appreciated.

I have the following custom objects:
Candidate
Employment Website
Job Application
Position
Review (master object - Job Application)
Job Posting (master object - Position, Employment Website)

<apex:page standardController="Position__c">
This map shows the locations of candidates who have applied for the {!Position__c.Name} position.
