I'm having difficulty using the action settings to drill down another report from the chart control.  I would like to pass a parameter to the second report using a value from the data displayed in the chart.

I have tried the action settings on both the axes and the data area however neither work:

If I use the action settings of the axes, then the next report is shown but the parameter value passed does not reflect the item selected from the axis.

If I use the action settings of the data area, then the report fails to load, and the following reporting services error is generated: "The Required Field Name is missing from the input structure".

There does not appear to be any documentation for the action settings so I'm not sure what I'm doing wrong.

Regards,

Michael.
