Hi, I checked the link you sent, but I’m not sure I understand.
Where do you want the map to appear? At the top? It’s too wide for the column.
The theme is applying CSS ‘float:left’ to everything to make the columns.
What happens if you create the page *without* the columns?
Some things to try:
1. Put the map shortcode on its own line, if you haven’t already. It should look like ths in the html editor:
2. If you want the map to NOT float, you can apply some CSS before or after it:
3. You can check the CSS by using IE debugging tools or Firebug for Firefox
