GMap View blank

I have the following installed
Views 6.x-2.6
Location 6.x-3.1-rc1
GMap 6.x-1.x-dev

I have about 500 nodes with a CCK location field. The edit view of the node shows a GMap with a flag at their respective L/L.

I made a view, filtering on the type of node and published, with the display field as the Title/link. I made a page from the view.

When I view the page with the style set to list, I get 500 titles listed. When the style is set to gmap, I get a blank page.

the generated html for the content div

looks empty to me???
