Hi Michele,
For performance reasons, in Crystal Reports XI Release 1 and Release 2 the maximum number of values that are returned for a list of values is set to 1000. If you have a cascading List of Values (for example Country > Region > City), the lowest level (in this case City) will only display a maximum of 1000 values. This means that the higher-level prompts may display far fewer values than you expect. The list of values provides the data for the dynamic parameter list.
