Well you seem to be at least one step further on then.
That action is set to trigger at both locations at any time and suppress for one second. Therefore any issues are now likely to be due to your setting of the location.
From Places you should be able to add a new location, then tap location, zoom in on the map to set the geofence location you want to use, enter a name, and then done; you have a new entry on your list.
Anything beyond that and you really are going to have to provide some precise details about the nature of the issue you are facing.
Technically there are many ways in which these things will fail, and in order to pin it down takes as much detail as possible. I’m assuming in this case that it didn’t trigger even after leaving the desired area and returning to it. Regardless, I’m hopeful the above example will set you on the right track for specifying your locations correctly.
Once your locations are set, you then just assign them to your actions with the appropriate timing entry/exit and timing parameters.
