I get an object improperly defined error on this line. The UID variable does have the correct value. I checked it. The datatype is consistent with the stored proceedure I am calling and with the table the recordset is in. Does anyone know what could be my problem?<BR><BR> adoCmd.Parameters.Append adoCmd.CreateParameter("UID", _<BR> adUniqueIdentifier, adParamInput, 16, _<BR> UID)<BR>
