TimW,
Thanks so much for the quick reply. I went back and uploaded the map to ArcGIS Online as a tiled service and it completed the upload, but gave me this message:
"The cache for the service has been enabled but the cache generation failed."
I tried it a few times and always got this message. The map I was working with is not large in size (it contains about 850 point features) but it has a pretty large extent in that the points are spread across most of the United States.
So, that leads me to a couple of questions. How do I fix the cache generation error and if I am successful in that regard, is there any way to know or estimate how many credits will be consumed by creating such a map? Also, would the credits be consumed only when the map/cache is originally generated or everytime the map is used/viewed on the web? Thanks again. Any help is greatly appreciated.
