You would be best off if you used a function. In your query, create a column with something like LineCount : GetLineCount([ida], [idb], .8)

 I'm passing .8. If this number changes, you can change the value in the query and the function will calc correctly.

 Then in the modules create a function called GetCount(). Aircode is: Public FUnction GetCount(strIDA As string, strIDA2 As String, _  dblDec As Double) As Integer Dim strSQL As STring Dim rst As Recordset Dim dblVal As Double

 'select records for the ids strSQL = "Select number from ... " & _  "Where ida = strIDA and idb = strIDB" "order by number decending"

 set rst = currentdb.openrecordset(strSQL...) rst.movefirst Do while not rst.EOF 'add the number from the select dblVal = dblVal + Number

 'increment line count GetCount = GetCount + 1 'if greater/equal, .8 line count reached If dblVal >= dblDec Then exit do endif rst.MoveNext loop End Function

I addressed the same thing but put it in the code behind a button. I set up a field named last number. I needed to add a number of records at once so set up a loop. I added 1 to last number each iteration. Not sure if its the same thing aswhat you want to do but here's some code:

Dim Number1 As IntegerDim Number2 As IntegerDim IncNum As Integer

Number1 = 1Number2 = Forms!formname!Txtfield

IncNum = IIF(IsNull(DLookup("MaxofLastNumber", "LastNumLookUpQRY")), 0, DLookup("MaxofLastNumber", "LastNumLookUpQRY")) ' this is important only for the first record.

For i = Number1 To Number2 'sets up the loop and tells it how many times to runbased on data entry in the form text box

Set db = CurrentDbSet rs = db.OpenRecordset("Tablewhereyouwanttochangeinfo")rs.AddNew 'opens a new recordrs("LastNumber") = IncNum + i 'adds the number (ie if it is running the 5th loop

 it adds 5) to the incnum value and places it in the last number field.
