[AccessD] SQL table update error

    Good Morning,
 
I have attached a sql table in my access 2007 database.  I can copy and paste records into just fine; how ever when I try to write to it using vba I receive the error "Run-time error '31456':  ODBC--call failed."
 
Here is my code:
 
Dim rstRSs As DAO.Recordset
    
 Set rstRSs = currentdb.OpenRecordset("dbo_InternalPhoneRecord", dbOpenDynaset, dbSeeChanges)
 
 With rstRSs
.AddNew
![IPRdatecalled] = datCallDateTime
.Update
 End With
 
I receive the error on the .Update statement.
 
 
Does anyone have any idea?
 
Thanks!
