Thanks for your reply. I am still confused as to whether when you stand on a scale you are pushing the spring down, which sounds more likely or whether as is written in some books, the spring is pushing up. Also is your weight measured from the scale pushing up, or from your weight pushing down. I appreciate the clarification so I can really understand how the scale works.
Both! You push the spring down and in return, it pushes you back up.

All forces come in similar pairs.
