Macro to sort variable rows of data by a column in multiple sections

Hi mannuhs

Sort syntax is different for Excel 2007. This syntax will work in either. You indicated to sort through Column O but your Data extends to Column R so that's what I used. If you truly want Column O change the rng references.
Let me know of issues.

Option Explicit

Sub SortStuff()
    Dim LR As Long, piRow As Long, CERow As Long, VOSRow As Long
    Dim ws As Worksheet
    Dim rng As Range
    Set ws = Sheets("Sheet1")
    With ws
        LR = .Cells.Find("*", .Cells(.Rows.Count, .Columns.Count), SearchOrder:=xlByRows, _
                SearchDirection:=xlPrevious).Row
        piRow = .Columns("A").Find(what:="P1 Level Calls", LookIn:=xlValues, lookat:=xlWhole).Row
        CERow = .Columns("A").Find(what:="Vendor CE Meet", LookIn:=xlValues, lookat:=xlWhole).Row
        VOSRow = .Columns("A").Find(what:="Vendor On Site", LookIn:=xlValues, lookat:=xlWhole).Row
        Set rng = .Range(.Cells(piRow + 1, 1), .Cells(CERow - 5, "R"))

        With rng
            If rng.Rows.Count > 1 Then
                .Sort Key1:=.Cells(piRow + 1, "J"), Order1:=xlAscending, Header:=xlGuess, _
                        OrderCustom:=1, MatchCase:=False, Orientation:=xlTopToBottom, _
                        DataOption1:=xlSortNormal
            End If
        End With

        Set rng = .Range(.Cells(CERow + 1, 1), .Cells(VOSRow - 1, "R"))

        With rng
            If rng.Rows.Count > 1 Then
                .Sort Key1:=.Cells(CERow + 1, "J"), Order1:=xlAscending, Header:=xlGuess, _
                        OrderCustom:=1, MatchCase:=False, Orientation:=xlTopToBottom, _
                        DataOption1:=xlSortNormal
            End If
        End With

        Set rng = .Range(.Cells(VOSRow + 1, 1), .Cells(LR, "R"))

        With rng
            If rng.Rows.Count > 1 Then
                .Sort Key1:=.Cells(VOSRow + 1, "J"), Order1:=xlAscending, Header:=xlGuess, _
                        OrderCustom:=1, MatchCase:=False, Orientation:=xlTopToBottom, _
                        DataOption1:=xlSortNormal
            End If
        End With
    End With
End Sub
