How to insert GMap macro to a page in Drupal with Gmap module?

I creat开发者_Go百科ed a GMap macro but I do not know how to insert it on the page. When I try to put it in the body field of a page, it does not work. Any ideas?

Do you have the GMap macro filter turned on in your input format of choice?

For example, if you edit Full HTML, it should have a list of options like HTML Filter, Link Filter, etc. When you enable Gmap on the input format, it can then parse those macros.
