unable to populate combobox using .rowsource {vba excel}

Question

I'am a newbie in VBA excel and trying here to populate a combobox in a userform with data from a sheet. I defined address & used the .rowsource property wherein code go through without any error but nothing populates on the combobox. Any help will be appreciated.

Below is the code -

Private Sub empSearchdb_Click()

Dim cell As Range
Dim emptyRow As Long
Dim rng As Range
Dim ws1 As Worksheet
Dim empSearchKeyword As String

'Stop screen flickering
Application.ScreenUpdating = False

'setting worksheet
Set ws1 = Sheets("EmployeeDetails")
ws1.Activate

'find last empty row
emptyRow = WorksheetFunction.CountA(Range("A:A")) + 2

'when nothing is selected
If Me.empSearchL.ListIndex = -1 Then

    'from $A$1 to $J$lastrow-1
    Set rng = Range("$A$1", Cells(emptyRow - 1, 10))

    With Me.empDetails
        .RowSource = rng.Address
    End With

New modified code -

Dim cell As Range
Dim emptyRow As Long
Dim rng As Range
Dim ws1 As Worksheet
Dim empSearchKeyword As String

'Stop screen flickering
Application.ScreenUpdating = False

'setting worksheet
Set ws1 = ActiveWorkbook.Sheets("EmployeeDetails")

'find last empty row
emptyRow = WorksheetFunction.CountA(Range("A:A")) + 2

'from $A$1 to $J$lastrow-1
Set rng = ws1.Range("$A$1", ws1.Cells(emptyRow - 1, 10))
Set rng = ws1.Range("$A$1", "$J$10")


'With your listbox do the following
If Me.empSearchL.ListIndex = -1 Then
    With Me.empDetails
        'If nothing is selected, add a row source
        .ColumnCount = 10 'Otherwise you will only get 1 column
        .RowSource = rng.Address
    End With
End if
Application.ScreenUpdating = True
