You are messing up the #geocode and #display_point syntax.

Using the yahoo geocoding service for #geocode is done like this:
{{#geocode:Moscow, Russia|yahoo}}

If you want to set the geocoding service for display_map or display_point(s), use the geoservice parameter.

If you want to use yahoo maps instead of google maps, just use service=yahoomaps. This will also cause Maps to use the yahoo geocoding service, so you don’t have to specify it explicitly.

But I’m having trouble getting display_points to work correctly.
Here’s my wiki code:
Coords : {{#geocode:Moscow, Russia}}

{{
#display_points: Moscow, Russia~Russia~Russia is Nice;Paris, France~Paris~Gay Pairee|yahoo
}}

{{
#display_points: Berlin, Germany; New York, NY~NY~The Big Apple|yahoo
}}

{{
#display_points: Berlin, Germany; New York, NY~NY~The Big Apple
}}

{{#display_points: 55.756870, 37.615101~coordinates~I used coordinates here}}

{{
#display_points:
Moscow, Russia~Moscow~A city in Russia
}}

{{
#display_points:
service=yahoomaps
|address=Moscow, Russia; New York City
|zoom=7
|width=800
|height=500
}}

When I save that, I see:
- Coordinates correctly determined
Map 1 – Map is centered in australia somewhere, there’s a label baloon in the middle with no text
Map2 – the same
Map3 – No map, no zoom tool. I have direction arrows, map/sat/hybrid buttons, and a label baloon in upper left corner. So even though I’ve set yahoo as my default, something strange happens when I don’t specify the map api in the function call
maps 4 and 5 display fine, though at different zoom levels
map 6 , looks the same as map 3 (blank), but just a bit larger.

Any idea what I may be doing wrong here?

thanks again for all your hard work.
