'SECT' is not an index in this table???

[TSC]

I get the following message in the Crystal Report Viewer
whenever I attempt to execute my reports:

'SECT' is not an index in this table???

This message is followed up by:

Error detected by database DLL.

Could someone please explain to me what is happening here
and how to resolve it? I examined the SECT field in the
database and there is not an index set upon it. My reports
were created using the RDC in Visual Basic 6.0. The
database that I am trying to access was created in MS
Access 2000.

Thanks,
TSC
