Description
The error has an associated description (e.g., field does not exist, table is incomplete, invalid dataset, invalid number of datasets, etc.)
Solution
Review datasets and input parameter values, and correct according to specific error message. If you are using a geostatistical layer created in ArcGIS 9.1 or earlier, and the link to the dataset that was used to create the layer has been broken, you should add the layer to the Contents pane and repair the data link before rerunning the tool.
