Hi, I had looked time and time again at this, but I came up with a solution (with the help of others) here http://support.advancedcustomfields.com/forums/topic/yoast-seo-acf/
However, I’m sorry to say that it seems that Yoast has changed his method of doing things and it seems to be not working at the moment again 🙁
