Installing Google Analytics

I'm trying to install the Google Analytics extension, but I do not have the mj_all_footer2 position as an option. I typed it in, but I don't see the code for the analytics when I go to view source. 

Do I need to add that position?

I'm confused about this as well. I don't have mj_all_footer2 so I put it on mj_all_footer and it seems to be working because when I look at the source of the page I see "mj_googleanalytics" for different user gadgets but I don't know if its actually working. Can someone please confirm on how we install this?

Thank you for a great product!

PS. I've also noticed there is a whit dot know in that position the page?

*bump- I would really love to knwo the answer to this

Joomla populates list of position using nonempty positions (with modules), positions of default template, and positions of templates assigned to menus. Any other names are not included in the list.

Thank you for responding. But I'm not sure that you answered the question, at least in terms my mind will understand. lol So you saying that we should only put in a model that is listed and ignore the instructions to put in in position mj_all_footer2?

Correct position name is mj_all_footer.
PS. First version of docs included mj_pda_footer2 as a position name, but further it was renamed to mj_all_footer keeping incorrect trailing 2 in the docs.
