I'm trying to get the ratings for a list item in a custom list, using the GetRatingOnUrl method. List is rating enabled. I'm accessing this method via the SPServices jquery library. I'm not sure how to set the URL parameter. Currently I'm setting the url this way:
since this is how the item was appearing in the FieldRef. I tried setting the URL without the '_.000' too.
I get this error:

Server was unable to process request. ---> Attempted to perform an unauthorized operation

Can somebody tell me what I'm doing wrong? Thanks.
