Populating global map with "events-manager" events

Hi,

I am trying to map events that have been created with the events-manager plugin. I think i am doing everything right: I have tried using the “Collect Location For” option on the setting > Overall tab, but for some reason nothing gets mapped.

I would like to try using the “Geocode Custom Field”, but i have no idea what fields need to be input. I am not even sure that would be the best way to go about solving this issue.

Could anyone help me out with this ?

Many thanks,
Yvan
