Exiting Excel using VBA throws runtime error 424

I was writing a VBA macro that opens an HTML document in Excel (to perform various calculations on it). Excel will search for an HTML document in the current folder. If it cannot find it there, it will create a file open window where the user can manually find the location of the HTML document. So far so good. However, if the user chooses Cancel (instead of selecting the file), I want Excel to display a message and exit.

The message is generated, but then the code stops with the following error:

Run-time error '424': Object required.

It doesn't seem like too much of a hassle, but I am running into one brick wall after another trying to figure out what is causing the problem.

A submarine that just doesn't work:

Sub ExitWithoutPrompt()

MsgBox "You failed to select a file, therefore Excel will now close.  Please refer to the readme file."
Excel.Application.DisplayAlerts = False
Excel.Application.Quit

End Sub

      

        
        
        
      

    

I am using MS Excel 2002, but I need the solution to work on as many Excel variants as possible.

Any help gratefully received as to where I am going wrong. I'm a complete newbie by the way, so if possible please be bored with any guidance you may have for me ...

Since it might be useful, included below (at the risk of making this post unwieldy) are two other routines that I use in the macro:

First sub:

Sub Endurance()

Call OpenHTML

Range("G27").Value = "Category"
Range("G28").Value = "Meat"
Range("G29").Value = "Veg"
Range("G30").Value = "PRP"
Range("F27").Value = "Fleet"
Range("E27").Value = "Consumption"

Range("E32").Value = "Endurance"

Range("E33").Value = "Lowest Category"
Range("E34").Value = "Fleet"
Range("E35").Value = "Consumption"

Range("E27, F27, G27, E32").Font.Bold = True
Range("F28").Value = WorksheetFunction.Sum(Range("E8,E9,E11,E14,E21"))
Range("E28").Value = WorksheetFunction.Sum(Range("G8,G9,G11,G14,G21"))
Range("F29").Value = WorksheetFunction.Sum(Range("E10,E16"))
Range("E29").Value = WorksheetFunction.Sum(Range("G10,G16"))
Range("F30").Value = WorksheetFunction.Sum(Range("E20,E22"))
Range("E30").Value = WorksheetFunction.Sum(Range("G20,G22"))

Columns("E:F").EntireColumn.AutoFit

Range("G28:G30, E27, F27, G27, G33").Select
    With Selection
        .HorizontalAlignment = xlRight
    End With

Range("E27:G30, E32:G35").Select
    Selection.Borders(xlDiagonalDown).LineStyle = xlNone
    Selection.Borders(xlDiagonalUp).LineStyle = xlNone
    With Selection.Borders(xlEdgeLeft)
        .LineStyle = xlContinuous
        .Weight = xlThin
        .ColorIndex = xlAutomatic
    End With
    With Selection.Borders(xlEdgeTop)
        .LineStyle = xlContinuous
        .Weight = xlThin
        .ColorIndex = xlAutomatic
    End With
    With Selection.Borders(xlEdgeBottom)
        .LineStyle = xlContinuous
        .Weight = xlThin
        .ColorIndex = xlAutomatic
    End With
    With Selection.Borders(xlEdgeRight)
        .LineStyle = xlContinuous
        .Weight = xlThin
        .ColorIndex = xlAutomatic
    End With
    Selection.Borders(xlInsideVertical).LineStyle = xlNone
    Selection.Borders(xlInsideHorizontal).LineStyle = xlNone


Dim Endurance As Double
Endurance = WorksheetFunction.Min(Range("F28:F30"))
Range("G34").Value = WorksheetFunction.RoundDown(Endurance, 0)

Endurance = WorksheetFunction.Min(Range("E28:E30"))
Range("G35").Value = WorksheetFunction.RoundDown(Endurance, 0)

Range("G33").Value = Endurance

Dim LowCat As String

LowCat = WorksheetFunction.VLookup(Endurance, Range("E28:G30"), 3, False)
Range("G33").Value = LowCat

ActiveSheet.PageSetup.PrintArea = "$A$1:$G$35"
ActiveSheet.PageSetup.Orientation = xlLandscape

Range("G36").Select

If MsgBox("Print endurance statement?", vbYesNo + vbDefaultButton2, "Print endurance") = vbYes Then
    ActiveWindow.SelectedSheets.PrintOut Copies:=1
    Else
    Range("G36").Select
    End If


End Sub

      

        
        
        
      

    

And the second sub:

Sub OpenHTML()

On Error GoTo MissingFile

Workbooks.Open FileName:=ThisWorkbook.Path & "\TRICAT Endurance Summary.html"


Exit Sub

MissingFile:

Dim Finfo As String
Dim FilterIndex As Integer
Dim Title As String
Dim FileName As Variant

' Set up list of file filters
Finfo = "HTML Files (*.html),*.html," & _
        "All Files (*.*),*.*,"

' Display *.html by default
    FilterIndex = 1

' Set the dialog box caption
Title = "Select TRICAT Endurance Summary"

' Get the filename
FileName = Application.GetOpenFilename(FInfor, FilterIndex, Title)

' Handle Return info from dialog box
If FileName = False Then
    Call ExitWithoutPrompt
    Else
    MsgBox "You selected" & FileName
    Workbooks.Open FileName

End If

End Sub

      

        
        
        
      

    

If yours is that far, thanks for reading ....
