Create place mark by longitude and latitude

Hi,
I've been creating a map for my scuba diving website and creating place marks to show dive sites.
So far I've created over 100 place marks, but it's very slow as I'm dragging the maker around until I get the latitude and longitude to match what I have in my list of dive sites.
When I try to enter in the latitude and longitude in the component to create a place mark I get the following error message...
"Geocode was not successful for the following reason: ZERO_RESULTS
for address:"
Is there a setting I can change somewhere to allow me to fix this?
Thanks, your extension is fantastic.

Hi
I'm not clear understand you.
If you create new placemark in admin panel of component, you just click on map, and will get the latitude and longitude. And there is a search field with autocomplete feature to find place, and it will suggest you text address, when you select it the lat/lng will set for placemark too.

IF you mean that map will long time to load on site, then enable Dynamically loading map objects in map details to JQuery and set buffer size for example to 100. In this case page will not contain code to placemark creation and will be loaded fast.

If you mean you get ZERO_RESULTS message when displaying map on site page, it can cause from placemark, defined by text address - than just drag it's marker on map in admin panel in placemark details to get lat/lnd.

Hi Dima,
I have a list of lat/lng that I want to put place marks on the map. I was just wondering if there's a way I can enter the lat/lng to put the place mark exactly in that location on the map rather than dragging it around.
As this is dive sites the locations are all ocean so it's hard to click in the correct place unlike a house for example on the land.
If this is not possible then I can continue in the usual way, it's just a slow process to get them all in their correct placement.
Thanks again,
Tony

Hi.

If you want, you can load it. See tutorial.

But if you have created your placemarks, you have to change it manual. Or write update clause in mysql
