make a dynaset querydef updateable

I need to update a field that is in a querydef.  I have 2 queries.
query 2 is based on query 1. The problem is an error occurs "recordset is read only"
I have looked up the dynaset updateable property and is says that it can be updated.
the first query can be edited but the second can't.  how can I get this second query to be updateable?.  Are compounded queries read only??? is it because it is based on "dates" and the update property can only update the field of its original table.?
 icdpSQL = "SELECT tblSlideDetail.ToSchedule, tblOrders.ProjectName,..... " & " between #" &       DATE1 & "# and #" & DATE2 & "#))ORDER BY tblSlideDetail.CompletionDate;"

iccycleSQL = "SELECT [Dates].ProjectName, count([Dates].ItemID) as countofitemid,             [Dates].Available, [Dates].ToCycle FROM [Dates] GROUP BY [Dates].ProjectName,             [Dates].ItemID, [Dates].Available, [Dates].ToCycle;"

    Set icdpQD = dbs.CreateQueryDef("Dates", icdpSQL)
        With icdpQD
            Set icdpRS = icdpQD.OpenRecordset(dbOpenDynaset)
        End With
    Set iccycleQD = dbs.CreateQueryDef("Cycles", iccycleSQL)
        With iccycleQD
            Set iccycleRS = iccycleQD.OpenRecordset(dbOpenDynaset)
        End With
        With iccycleRS
            Do Until iccycleRS.EOF
                If iccycleRS!countofitemid > (iccycleRS!Available * 2) Then
                    itemover = iccycleRS!countofitemid - (iccycleRS!Available * 2)
                    totaldays = totaldays + itemover
                    increasedays = totaldays / numberofdays
                End If
               If iccycleRS!countofitemid > iccycleRS!Available Then
             '      this will set the cycle field for the mould that needs cycling
                   !ToCycle.Value = True
                End If

In your second query you have GROUP BY clause,this makes your query not updatable.Query can't be updated if it contains aggregate functions.

Thanks.  I've now had to create a 3rd recordset that is primarily the same as the first recordset icdpRS, except a few less fields and a where clause that includes a unique identifier of each record in the icdpRS.  in short, a modification was made and it works.
thanks.  the code would have been more efficient if I could have used the agregate query,
but oh well it works.
