msoFileDialogSaveAs not responding

[Datament]

I'm using a button "btnProcess" to save an excel file using MSOFileDialogSaveAS vba to open a file path for users to save to a folder in the open path or from there navigate to a desired path of the user. Below is what I have designed to open the path to \Acctstmt.

Every time I press btnProcess I get the error message "Compile error: Variable not Defined" highlighting "Set FDir = Application.FileDialog (msoFileDialogSaveAs)" in the vba code editor.

Please can you kindly review the below and please advise of what I am doing wrong or give me some suggestions related to MSOFileDialogSaveAs.

Dim MyExpFilename As String
Dim MyExpPath As String
Dim FDir As Object ' Used Object type instead of STRING for late binding
Dim strQ As String
Dim strF As String
Dim TempF As String
Dim OpenF_Path As String
Dim ExportF_Excel As String
Dim AppEx As Object ' Used Object type instead of STRING for late binding'
Dim myWork As Object ' Used Object type instead of STRING for late binding

TempF = "C:\RedGrows\ScheduledAcct\AcctStmt"

strQ = Chr$(34)
ExportF_Excel = "\8 Excel-" & Me.GetStore & Me.Ref
MyExpFilename = TempF & ExportF_Excel
OpenF_Path = strQ & TempF & "" & ExportF_Excel & ".xlsx" & strQ

DoCmd.TransferSpreadsheet acExport, acSpreadsheetTypeExcel12Xml, "qry_myCSVWork_Union", MyExpFilename, True

Set AppEx = CreateObject("Excel.Application")
Set myWork = AppEx.Workbooks.Open(OpenF_Path)
AppEx.Visible = True

With myWork
' Display Save As dialog to choose new location
Set FDir = Application.FileDialog(msoFileDialogSaveAs) 'Compile Error message highlights this line in the code editor
With FDir
.InitialFileName = MyExpFilename
If .Show = -1 Then
MyExpPath = .SelectedItems(1)

DoCmd.TransferSpreadsheet acExport, acSpreadsheetTypeExcel12Xml, "qry_myCSVWork_Unin", MyExpPath, True


End If
End With
myWork.Close True
End With

Set AppEx = Nothing
Set myWork = Nothing

Kill (TempF & "" & ExportF_Excel & ".xlsx")

You are using late binding, so the object has no idea as to what Application.FileDialog msoFileDialogSaveAs is, so either make it early binding, or find out what Application.FileDialog msoFileDialogSaveAs is as a numeric and use that.
Your choice?

BTW it would never be a string. It is an object, be it early/late bound

Make sure you have this reference set:

[Welshgasman]

TBH I have never found any definitive source as to what you need to include as a reference when trying to use functions like these? :-(

The object browser will often tell you.

The object browser will often tell you.

You need the reference loaded to be able to see that? and that is the issue, which reference?

[Welshgasman]

Thanks to Micron, that value is 2

Well ain't that dumb? An object browser that doesn't browse objects you haven't already have a connection to. Not the most intuitive at times, but I often go here to fill in the blanks.
