Hey Robert,

You missed one small step when setting up the databindings for the viewer.
You correctly went into the DataBindings dialog box and selected the cached
report. HOWEVER, on the left hand side of the dialog box, you should have
first selected the property "ReportSource". Instead, you left it at the
default property AccessKey. This results in the databindings trying to
assign the cached report to the AccessKey property instead of the
ReportSource property.

Once you fix that, you should be good to go!

HTH,

Brian Bischof
