Hi, I have tried to create a service that takes polygon / envelope as a parameter and returns string that contains URL to TiledPackage that is created by the python script but I cant get even prototype working. This is my first touch to python and ArcGIS Geoprosessing.I have created python script that takes polygon to extract and package name as a parameters. Then I have default values hard coded and then I call arcpy.ExportTileCache_management with those values. As a result, I get TiledPackage that is about size 164 kb regardless what polygon I give.I have cache stored on a external USB drive.Any pointers?

# Get parameters for the script
polygonToExtract = arcpy.GetParameterAsText(0)
packageName = arcpy.GetParameterAsText(1)
# Set default values for extract tool
cacheSource = r"L:\Taustakartta\Cache_taustakartta\Taustakartta\Taustakartta"
cacheTarget = r"T:\TilePackages"

areaofinterest = polygonToExtract
try:
arcpy.ExportTileCache_management(cacheSource, cacheTarget, cacheName, cacheType, storageFormat, scales, polygonToExtract)
