[RESOLVED] Sort an arraylist using compareTo

[jsublime]

I have a class with the following function:

 Public Function CompareTo(ByVal obj As Object) As Integer _
      Implements System.IComparable.CompareTo
        If Not TypeOf obj Is TicketData Then
            Throw New Exception("Object is not MyObject")
        End If
        Dim Compare As TicketData = CType(obj, TicketData)
        Dim result As Integer = Me.strSLA.CompareTo(Compare.strSLA)

        If result = 0 Then
            result = Me.strSLA.CompareTo(Compare.strSLA)
        End If
        Return result

    End Function

Presort I get the following data:

PRESORT
6721.04
3901.46
2768.12
2408.12
795.42
2377.29
2145.21
1866.25
1775.83

after running ticketList.Sort() I get:

SORTED
1.94
102.15
1180
129.58
13.54
133.33
139.17
148.33
1571.88

So it appears that my function is comparing as if it were a string. Can someone help me understand what I'm missing?
