`  ==Perhaps You Can Help== I am trying to create a note that is also a reference for an article. I am trying to put this reference link along with the words ``Ratings - Nielsen's in TV and Arbitron's in radio - help determine how much advertisers are charged to run commercials during TV programs and radio listening hours. The higher the rating, the more people there are watching and listening. That translates into a higher price for a commercial spot.`` I am trying to explain what references are in an article (which I hope to take to FAC) without going off-topic (and outside the scope of the article) in one of the sentences.  I have seen this done in other articles, but for the life of me I can't find any of them. Can you help? -  •  • `
