Repeat macro after UserForm Input - vba

Question

The macro ,upon opening the workbook, will look to see if cell "C27" contains any of the following Text: Location1, Location2, Location3, or Location4. If they do then it will continue to save 2 copy files of the template by those locations. If not then it will open a UserForm To select the correct location from a ComboBox.
How could i reset the check after the UserForm is closed, I tried Call Auto_Open after the Unload me but it didnt work.
Macro
Sub Auto_Open()
With Range("B30")
.Value = Time
.NumberFormat = "h-mm-ss AM/PM"

Select Case Range("C27").Value
Case "Location1", "Location2", "Location3", "Location4"
FilePath = "C:\Users\aholiday\Desktop\FRF_Data_Macro_Insert_Test"
FileName = Sheets("Data").Range("C27").Text
Application.DisplayAlerts = False
ThisWorkbook.SaveAs FileName:=FilePath & "\" & FileName
Dim FileCopyName As String
Dim FileCopyPath As String
Dim FileTime As String
FilePath = "C:\Users\aholiday\Desktop\Backup"
FileName = Sheets("Data").Range("C27").Text
FileTime = Sheets("Data").Range("B30").Text
ThisWorkbook.SaveAs FileName:=FilePath & "\" & FileName & Space(1) & FileTime & ".xlsx", FileFormat:=xlOpenXMLWorkbook
MsgBox "File was saved! Ready for Next Test, Please Exit."

UserForm.Show
Exit Sub

Application.DisplayAlerts = True

UserForm
Private Sub UserForm_Initialize()
'Empty TestLocation Box
TestLocation.Clear
'Fill TestLocation Box
With TestLocation
.AddItem "Location1"
.AddItem "Location2"
.AddItem "Location3"
.AddItem "Location4"
End With

Private Sub Insert_Click()
Sheets("Data").Activate
Range("C27").Value = TestLocation.Value

Unload Me

Answer 1

By using the following code for the insert button:
Private Sub Insert_Click()
Sheets("Data").Range("C27").Value = TestLocation.Value
Auto_Open
End Sub
The code will work (tested it), as long as you have the Auto_Open code in a module.
If you put the Auto_Open sub in the ThisWorkbook then move it to the module.
Then use the following code in ThisWorkbook:
Private Sub Workbook_Open()
Auto_Open
End Sub
Also:
Case "Location1", "Location2", "Location1", "Location4"
Should be:
Case "Location1", "Location2", "Location3", "Location4"
