I'm trying to use DisplayDataMap with geoshowdataby=geoshowbyzoomlevel but not work; give an error geography type

I've try same code with same import file with geoshowdataby=georegion1 or with geoshowdataby=georegion2 or with geoshowdataby=geopostal1 and it's all ok.

The file that import has name, latitude, longitude and data.

The same file imported with MapPoint Application work with zoom level

Somebody has used DisplayDataMap with geoshowdataby=geoshowbyzoomlevel ?

Thanks,
Rinaldo
