Update a table using variable - vba

Question

I'm pretty new to using VBA. I have an access database where the user clicks a button and this will upload multiple files.
The files uploaded are temp tables and get fields added to them etc. Once updates have been made to the temp tables, the records get transferred into a permanent table.
It uploads multiple files at once, so as files get uploaded the table they get input into tables called'temp_filename', with each file getting its own table.
Below is my code. For the alter table statement I want to upload the temp table which has just been created. As this table will be named something different every time I tried to assign it to a variable. I tried different syntax etc, however I keep getting errors. Can anyone see where I am going wrong? Any help would be appriciated.
Public Sub Import()
Dim oFileDiag As Office.FileDialog
Dim path As String: path = ""
Dim oFSO As New FileSystemObject
Dim FileSelected As Variant
Dim FileNameSelected As Variant
Dim UpdatedTableName As Variant
Set oFileDiag = Application.FileDialog(msoFileDialogFilePicker) ''Picks file to import
oFileDiag.AllowMultiSelect = True ''Allows multiple files to be selected
oFileDiag.Title = "Please select the reports to upload"
oFileDiag.Filters.Clear
oFileDiag.Filters.Add "Excel Spreadsheets", "*.xlsx, *.xls" ''Only allows xlsx and xls file types to upload
If oFileDiag.Show Then
For Each FileSelected In oFileDiag.SelectedItems
FileNameSelected = oFSO.GetFileName(FileSelected)
UpdatedTableName = "temp_" & FileNameSelected
If oFileDiag.SelectedItems.Count > 0 Then path = oFileDiag.SelectedItems(1)
If Len(path) > 0 Then
DoCmd.TransferSpreadsheet acImport, acSpreadsheetTypeExcel12, UpdatedTableName, path, 1
DoCmd.RunSQL "ALTER TABLE UpdatedTableName ADD COLUMN [Date_of_Report] TEXT(100);"
MsgBox "The " & FileNameSelected & " file has been uploaded"
Else
MsgBox "File not found"
End If
Next
End If

Answer 1

You need to concatenate the table name into the SQL string:
DoCmd.RunSQL "ALTER TABLE [" & UpdatedTableName & "] ADD COLUMN [Date_of_Report] TEXT(100);"
I've used square brackets just in case there are things like spaces in the table name.
