Excel 2000

I am trying to get AutoFilter data into a ListBox.
The below code gives me an "Type mismatch" error when I try to add the
Listbox Rowsource line. I read about using _FilterDatabase but could
not get the right syntax.

Private Sub UserForm_Initialize()
Dim myVisibleRng As Range
Dim myFilterRng As Range
Set myFilterRange = Sheet1.Range("a1:e13000")
myFilterRange.AutoFilter Field:=5, Criteria1:="18650"
Set myVisibleRange = myFilterRange.SpecialCells(xlCellTypeVisible)
Debug.Print myVisibleRange.Address
ListBox1.RowSource = myVisibleRange '<--type mismatch
End Sub


Thanks.
