Sum acreage on selection?

I would like to create a geoprocessing model/script to sum acreage (a field) for selected parcels, ultimately in an ArcGIS Server (10.0) web application. Is there a way to do this to display a popup, similar to the attribute table Summary Statistics window in ArcGIS Desktop, without the need for an output table/workspace? Has anyone else already done this, and willing to share your information?

While it would be easy enough to create a model that generates the sums, it probably would not function quite the way you want.  You probably need to pick what type of Web Front End you want (javascript, Silverlight, Flex, etc) and then repost in that forum because this is not really trivial.

If you were using Flex, I would look at the following example on selecting parcels and then possibly look into using the following method (second link) for getting geometries to add up and probably display in your widget window.  Perhaps someone else has done it already though.

Thanks NeoGeo, but I am simply using the ArcGIS Server Manager 10.0 web application wizard. So, I got a model to basically do what I want from within the web application, but only writes the "Acreage" table to a geodatabase at specified location. I don't imagine there is a way to have the default web application builder interact more with the user, though. I would prefer to have the model open the table by default as well, from within the web application. I guess you are right, that if I expect anymore I must create a custom web application with an ArcGIS API / IDE.

Have your model do a table join to join the summary results table to your data layer and then try to do your popups off of that.  Not sure what web front end you want to use but the Flex Application Builder appears to have some out of the box options for configuring renderers and popups for your geoprocessing results.
