Open word file from userform with folder and file names as per textbox values

Hi all,
I am trying the following:
1. Open a word document from userform
2. name of folder is as per textybox2 and file will be as per textbox1

Following code will take as far as general folder, but unable to go any further.

Private Sub CommandButton2_Click()
 Dim SelectedFile As String
    
    With Application.FileDialog(msoFileDialogFilePicker)
        .Title = "Select required files"
        .AllowMultiSelect = False
        .InitialFileName = "C:\123456\"
      ' this 123456 will need to be as per textbox2
  .Filters.Clear
        .Filters.Add "Word Documents", "*.docm", 1
   'The file name will be as per textbox1.docm

  If .Show Then
        SelectedFile = .SelectedItems(1)
        Me.TextBox1 = SelectedFile
     ' then I want that document opened

 Else
        MsgBox"Processing terminated."
              Exit Sub
      End If
    End With
End Sub

Code in userform1

Option Explicit

Private Sub Worksheet_BeforeDoubleClick(ByVal Target As Range, Cancel As Boolean)
Dim frmUpdate As UserForm1

Cancel = True

If Not (Intersect(Target, Columns("A")) Is Nothing) Then
    Set frmUpdate = New UserForm1
    Set frmUpdate.TargetSheet = ActiveSheet
    frmUpdate.CurrentRow = Target.Row
    frmUpdate.Show
    Set frmUpdate = Nothing
End If



End Sub

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
    Dim ColCtr As Double
    For ColCtr = Cells(, "L").Column To Cells(, "AA").Column
        If Cells(Rows.Count, ColCtr).End(xlUp).Row < 3 Then
            Columns(ColCtr).EntireColumn.Hidden = True
        Else
            Columns(ColCtr).EntireColumn.Hidden = False
        End If
    Next ColCtr
End Sub

I have attached the file.
