VS 2005 not recognizing variable use

[flycast]

I just upgraded to VS.NET 2005 and it looks good except the compiler is warning me that I am declaring variables and not using them when I actually am. It is giving me "Unused local variable" on TimeMark, ExcelValues, points, X, Y in the following code:

Dim Progress As New ProgressForm("Writing to Excel")
        Progress.MaxValue = FinalDataArray.GetUpperBound(0) + 1 - Trigger
        Progress.StepValue = 1
        Progress.Open() 'Open progress bar
        Dim TimeMark As Double = 0
        Dim ExcelValues(FinalDataArray.GetUpperBound(0)) As Double
        Dim points As New ZedGraph.PointPairList
        Dim X As Double
        Dim Y As Double
        For i = Trigger To FinalDataArray.GetUpperBound(0) + 1
            Application.DoEvents()
            X = TimeMark
            Y = Conversion.Convert(FinalDataArray(i - 1), Conversion_Class.Type.Weight)
            points.Add(X, Y)
            TimeMark += Increment
            Progress.Increment(1)
        Next
        Progress.CloseForm()

What's up with this?
