Formatting output in VB

[ice]

Ok, so I have this set of data and everything, but I want to format the numbers into percentages and actual numbers. I tried doing this in the "fmtStr" by putting a

:P0

after the numbers but it does nothing. Anyone know why?

    Private Sub btnDisplay_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDisplay.Click
        Dim fmtStr As String = "{0,-10}{1,12:N0}{2,14:N0}{3,12:N0}{4,14:N0}{5,14}"

        With lstGender.Items
            .Clear()
            .Add(String.Format(fmtStr, "Age Group", "Males", "Females", "%Males", "%Females", "%Total"))
            .Add(String.Format(fmtStr, "Under 25", "51210", "48905", "51.15", "48.85", "34.80"))
            .Add(String.Format(fmtStr, "25-64", "74169", "77059", "49.04", "50.96", "52.56"))
            .Add(String.Format(fmtStr, "65+", "15319", "21051", "42.12", "57.88", "12.64"))

        End With
    End Sub
End Class

EDIT: Idiot, I think I know what I did. I put the numbers in quotes too, so that changed them to string values and strings aren't touched with formatting.

yeah you shouldn't need to put the numbers in quotes.

Yeah that was what did it. I just kept going with the quotes because I started out with them.
