Multiple Combo Box Drop down

I am trying to create a table with dropdown lists. To help users, I would like to make use of combo boxes for its autofill functionality.

Currently I have a code for the combo box. This code calls for the combo box whenever a cell in a given table column is double-clicked.

My table has 4 columns that I would like for this code to work. 1. Employee Name 2. Employment Status 3. System Name 4. Access Rights

Needless to say, I have also created four (4) combo boxes for each column. So far, my code only works for one column and does not work if I have four.

I only copied the code online and tried to modify it but somehow I can't make it to work.

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

Dim str As String Dim cboTemp1 As OLEObject Dim cboTemp2 As OLEObject Dim cboTemp3 As OLEObject Dim cboTemp4 As OLEObject Dim ws As Worksheet

If Selection.Count = 1 Then

          With cboTemp1
          'clear and hide the combo box
            .ListFillRange = ""
            .LinkedCell = ""
