Google Maps / What's Going on who Support??

I keep getting disconnected and having super long wait times, which is no fun.

I am trying to post the exact same Google Map on two different pages in two different sizes. I have looked at the documentation which shows me how to do a lot of wonderfully fancy things but it seems to me all I need to do to change the size for the particular page is to go under options and change it,,, right? But when I do that, it changes the original map in every location where I’ve placed it, not just in its current embed. How do I just change the size on the current page where I’m embedding the map?
