Cant get custom field or map zoom to work, need help please!

Hello,

I have tried installing and uninstalling several times but I cant get this plugin to work for the life of me.

The 2 things I needs the most dont work.....I cant get it to work with a custom field even tho I have it checked and the name of the field and also the default map zoom doesnt work on the widget. It just shows the complete north & south america map.

I really need this for a project, any help would be appreciated. I can give login info to access my site.

Thanks!
