Match Function Problem!!! (RESOLVED)

[Avatarp]

VBA Excel

I keep getting an Error 2042 returned by the match function here. I have carfully set my Range variables to the correct columns and rows. The range objects are all dates. It seems no matter what I do I get that error. Any ideas? Here is the code:

Sub test()
    Dim matchstart As Range
    Dim matchend As Range
    Dim matchRange As Range

    c = CDate("1/28/2004")

    Set matchstart = Workbooks("datafile.xls").Sheets("futexpiry").Cells(2, 5)
    Set matchend = Workbooks("datafile.xls").Sheets("futexpiry").Cells(500, 5)
    Set matchRange = Workbooks("datafile.xls").Sheets("futexpiry").Range(matchstart, matchend)
    FirstMatch = Application.Match(c, matchRange, 1)
End Sub
