Single item on day

Hi:

I would like to be able a single item on a Day within a day range. Then, have a running total of the numbers in the date range.

The problem is when the date is clicked on multiple times it adds items to the Array so that affects the total count even though one can only SEE one item.

*** Here is the CODE I am using  

procedure TfrmInserts.PlannerMonthViewCampaignDaySelect(Sender: TObject;
  SelDate: TDateTime);
var
    i: Integer;
    intTotalInsertions: Integer;

begin
    With PlannerMonthViewCampaign.CreateItemAtSelection do
    begin
        Text.Text := IntToStr(iDropInsertions);
        Planner.SetFocus;

        intTotalInsertions := 0;
        for i := 0 to PlannerMonthViewCampaign.Items.Count - 1 do
        begin
            intTotalInsertions := intTotalInsertions + StrToInt(Trim(PlannerMonthViewCampaign.Items[i].Text.Text));
        end;

        lblTotalInserts.Caption := IntToStr(intTotalInsertions);
    end;
end;

HERE IS A SCREENSHOT ***


The maximum number of items per timeslot is defined by:

PlannerMonthView.MaxItemsDisplayed. Default this is 3.
If you want to have scrollers that allow you to scroll within a range of items added in a timeslot, set
PlannerMonthView.ShowScrollColumn = true
