Gruss Excel help please

I use Betting Assistant(Gruss) linked to a excel spreadsheet and can get by writing my own formulas but when it come to vba code i am cr@p. 

I'm hoping that one of the kind souls on this forum can help me out with a what i believe will be a simple request adding to some existing code.

Basically i use this sample spreadsheet from the Gruss forum to load the quickpicklist at midnight then select the first race:

What i would like to add to this spreadsheet is when the first market is selected the second market is then selected 10 seconds later, the 3rd market is then selected 10 seconds later and so on... until the last race has been selected using the -1 trigger in cell Q2.
This can be achieved by using cell D1 which has the start time of the next race. When cell D1 has no time in it(not populated) the -1 trigger stops.

The existing code:

Private Sub Worksheet_Change(ByVal Target As Range)
    If Target.Columns.Count = 16 Then
        Application.EnableEvents = False
        If triggerQuickPickListReload Then
            triggerQuickPickListReload = False
            Range("Q2").Value = -3
            triggerFirstMarketSelect = True
        Else
            If triggerFirstMarketSelect Then
                triggerFirstMarketSelect = False
                Range("Q2").Value = -5
            End If
        End If
        Application.EnableEvents = True
    End If
End Sub


I've tried the Gruss forum and i find the forum like a morgue. Very hard to get anyone to help.

Any Betfairians out there who can sort this please?
