number on top of numbers

What i want to do is take data from columns "AA" and "BB" and have them inserted into the columns and rows to the left. The 1st event entered is AA=5 BB=10. AA determines which column and BB determines how many rows to fill. The 2nd event AA=6 BB=12 go to column "E" which is 6 and fill down to the number 12. Now when another event happens to have the same column AA=5 BB=15 column D which is 5 and add a 1 to rows 0-15. There may be as many as 50 events to calculate. If an event happens in the sane column several times it would be added to the data in those cells. I hope this explains. thanks in advance. Mark

What happens if there is an event such as A=5, B=12, that is less to fill than there was in a previous event?

Bob, Lets say the events in column "AA" were all 5 and there were 3 events. AA=5 BB=10,AA=5 BB=12, AA=5 BB=6 the rows would be filled like this. All 3 events went to 6, 2 events down to 10 and 1 event down to 12. Thanks for your time hope this helps. mark

Uum, that is different to what I expected

Try this

Private prevValue As Variant


Private Sub Worksheet_Change(ByVal Target As Range)


    On Error GoTo ws_exit


    Application.EnableEvents = False


    With Target


        If .Row > 2 Then
        
            If .Column = 21 Then


                If prevValue = "" Then
                
                    If .Offset(0, 1).Value <> "" Then
                
                        Call PopulateValues(.Value, .Offset(0, 1).Value)
                    End If
                End If
            ElseIf .Column = 22 Then


                If prevValue = "" Then


                    If .Offset(0, -1).Value <> "" Then
                
                        Call PopulateValues(.Offset(0, -1).Value, .Value)
                    End If
                End If
            End If
        End If
    End With


ws_exit:
    Application.EnableEvents = True
    Application.CutCopyMode = False
End Sub


Private Sub Worksheet_SelectionChange(ByVal Target As Range)
    prevValue = Target.Value
End Sub


Private Function PopulateValues(AA, BB)
Dim col As Long
Dim lastrow As Long
Dim i As Long


    With Me
    
        col = Application.Match(AA, .Rows(1), 0)
        lastrow = .Cells(.Rows.Count, col).End(xlUp).Row
        
            If lastrow > 1 Then
            
                .Range("AA1").Value = 1
                .Range("AA1").Copy
                .Cells(2, col).Resize(BB).PasteSpecial Paste:=xlPasteValues, Operation:=xlAdd
                .Range("AA1").Value = ""
            End If
            .Cells(lastrow + 1, col).Resize(BB - lastrow + 1).Value = 1
    End With
End Function

Thanks Bob i will give it a try. Looks complicated but I will do my best to figure it out. I will let you know, thanks for the time I really appreciate it. Mark
