I created a VF page to edit two fields on the Quote object. I need to make this page publically visible to customers and allow them to edit the two fields and submit the form. 
So far, the page and all fields are showing up publically, but when I try to add an ID to the URL and pull a specific record, I get an "Authorization Required" error message.
The guest profile has access to all fields for the Quote object, so I'm not sure what I'm missing
