I am having a problem with the Spatial Join tool (Tool box) at 10.0 SP5 ArcInfo, In the past I have used the tool to aggregate data from many small polygons to larger overlapping polygons through the field map  window setting the field to "Sum" and using JOIN_ONE_TO_ONE, resulting in a output that had the summation of the smaller polygons in the larger ones. In this case I am joining features "That have their center in" the Target feature.

Recent attempts at this have failed I end up with a join count of  1 and the values are not summed it only seems to count the 1st feature. my processing time is very short too so I know that it is not properly operating.

Attached is an image of the dialog box.
