How To Detect An Object

I am using a stored procedure that outputs multiple recordsets.
I use <% SET rsDisplay = rsDisplay.NextRecordset() %to step to the
next recordset.

In one particular condition the final recordset is not passed to the
page, so I need to detect that the object is empty.

I did just try <% If NOT rsDisplay.EOF Then %but I get:

Microsoft VBScript runtime error '800a01a8'

Object required

Any ideas how I can trap this error? I just want the area on the ASP
page not to display when there isn't a final recordset.
