Unable to upload a google map

Hi! I am trying to upload a google map to my site. For this I created both a simple pg. and a label title ; however, when I try to add the code to link the map (in Appearance), the cursor disappears and it does not allow me to type in the URL box the map pg. address. I tried the reverse too... open a label, place the code and then the title, and it will still not show on the screen (and I have saved and checked the public view). My site is mexicocityavantgarde.org. Thank you!

I'm not quite following what you are trying. Could you give the exact URLs to the pages where you are tying to upload the map? It'll be on the admin side, so we won't have direct access, but that will tell us where you are trying things.
